What is Hadoop?

In the previous articles of this blog, we people have seen the need and importance of big data and its application in the IT industry. But there are some problems related to big data. Hence to overcome those problems, we need a framework like Hadoop to process the big data. This article on Hadoop gives you detailed information regarding the problems of big data and how this framework provides the solution to bigdata. Let us discuss all those one by one in detail Importance of Big data: Big data is emerging as an opportunity for many organizations. Through big data, analysts today can get the hidden insights of data, unknown correlations, market trends, customer preferences, and other useful business information. Moreover, these big analytics helps organizations in making effective marketing, new revenue opportunities, better customer service. Even though this bigdata has excellent opportunities, there are some problems. Let us have a look at Problems with Big data: The main issue of big data is heterogeneous data. It means the data gets generated in multiple formats from multiple sources. i.e data gets generated in various formats like structured, semi-structured, and unstructured. RDBMS mainly focuses on structured data like baking transactions, operation data, and so on.  Since we cannot expect the data to be in a structured format, we need a tool to process this unstructured data.  And there are ‘n’ number of problems with big data. Let us discuss some of them. a)Storage: Storing this huge data in the traditional databases is not practically possible. Moreover, in traditional databases, stores will be limited to one system where the data is increasing at a tremendous rate. b)Data gets generated in heterogeneous amounts: In traditional databases, data is presented in huge amounts. Moreover, data gets generated in multiple formats. This may be structured, semi-structured, and unstructured. So you need to make sure that you have a system that is capable of storing all varieties of data generated from various sources. c)processing speed: This is a major drawback of leaving the traditional databases. i.e accessibility rate is not proportional to the disk storage. So w.r.t to data increment, access rate is not increasing. Moreover, since all formats of data present at a single place, the accessibility rate will be inversely proportional to data increment. Then Hadoop came into existence to process the unstructured data like text, audios, videos, etc.  But before going to know about this framework, let us have an initially have a look at the evolution Evolution: The evolution of the Hadoop framework has gone through various stages in various years as follows: a)2003-  Douge cutting launches project named nutch to handle billions of searches and indexes millions of web pages. Later in this year, Google launches white papers with Google File Systems(GFS) b)2004 –  In December, Google releases the white paper with Map Reduce c)2005 -   Nutch uses GFS and Map Reduce to perform operations d)2006  -  Yahoo created Hadoop based on GFS and Map Reduce with  Doug cutting and team. e)2007 -   Yahoo started using Hadoop on a  1000 node cluster. f)2008 -  yahoo released Hadoop as an open-source project to an apache software foundation. Later in July 2008, apache tested a 4000 node with Hadoop successfully g)2009 – Hadoop successfully stored a petabyte of data in less than 17 hrs to handle billions of searches and index millions of webpages. From then it has been releasing various versions to handle billions of web pages. So till now, we people have discussed regarding the evolution, now lets us move into the actual concept What is Hadoop? Hadoop is a framework to store big data to process the data-parallelly in a distributed environment. This framework is capable of storing data and running applications on the clusters of commodity hardware. This framework was written in JAVA. It is capable of batch processing. Besides this framework is capable of providing massive storage for any kind of data with enormous computing power. Moreover, it is also capable of handling virtually limitless tasks (or) jobs. This framework is capable of efficiently storing and processing large datasets from gigabytes to petabytes of data. Instead of using one large computer to store and process the data, Hadoop allows clustering multiple computers, to analyze the massive data sets in parallel more quickly. Here the data is stored on inexpensive commodity servers that run as a cluster. Its distributed file system enables concurrent processing and fault tolerance. This framework uses map reducing programming model for faster data storage and its retrieval from its nodes. Today many applications were generating the big data to be processed,  where the Hadoop plays a significant role in providing a much-needed makeover to the database world. Get more information on big data by live experts at Hadoop Online Training This framework has four components as mentioned below: HDFS – This stands for Hadoop Distributed File Processing Systems. This framework allows you to store data of various formats across the cluster.  This component creates the abstraction. Like Virtualization, you can see HDFS, as a single unit for storing big data. This framework uses a master-slave architecture. In HDFS is Name node is the master node and Data nodes is the Slave node. Name node contains the metadata about the data stored in Data nodes such as which data block is stored in which data node. Here the actual data is stored in data nodes. Moreover, this framework has a default replication factor of 3. Hence due to the utilization of commodity hardware, if one of the data nodes fails, HDFS will still have a copy of the lost data blocks. Moreover, this component also allows you to configure the replication factor based on your requirements. YARN: YARN stands for Yet Another Resource Negotiator. It is a Hadoop resource management. This component acts as an OS to the Hadoop.  This file system is built on the top of HDFS. It is responsible for managing the cluster resources to make sure that you don’t overload one machine. It performs all your processing activities by allocating the resources and scheduling the tasks. It has two major components i.e  Resource Manager and Node Manager. Here the Resource Manager is again a master node. Here the  Node Managers were installed on every Data Node. It is responsible for the execution of the task on every single data node. In the node section, each node has its node managers. Here the node manager manages the nodes and monitors the resource usage in the nodes. It receives the processing request and then passes the parts of the request to the corresponding node managers. Here the actual processing of the data takes place.   Here the containers contain the collection of physical resources like RAM, CPU (or) the hard drives. Map Reduce: a)It is a framework that helps the JAVA programs to do the parallel computation of data using Key-value pairs. Here the map is responsible for taking the input data and converts into the dataset that can be computed in a key-value pair. Here the output of the Map is consumed by the reducer, where there the reducer gives the desired result.  So in Map-Reduce approach, the processing is done at slave nodes and the final result is sent to the master node. Moreover, the data containing the code is responsible to process the entire data. Here the coded data is small when compared to the actual data. Here the code to process the data inform of Kilobytes. Here the input is divided into small groups of data called  Data Chunks. Likewise, each component of this framework has its own function in processing big data.  You people can get the practical working of this framework by live experts with practical use cases at Hadoop Online Course Final Words: By reaching the end of this blog, I hope you people have got on Hadoop and application in the IT industry. In the upcoming post of the blog, I'll be sharing with you the details on Hadoop architecture and its working. Meanwhile, have a look at our Hadoop Interview Questions and get placed in a reputed firm

What is IoT?

The way of people living in the 21st century has brought drastic change due to the high availability of the internet around us. There are multiple examples around us to explain how the internet has brought changes in our daily life. This article on IoT gives you detail information on how it has changed the people lifestyle and its application in today's world. We people have been probably hearing that IoT has brought the drastic change from operation to management and in some cases jobs automation in all industries. How this platform has brought this drastic change? What made this change? Do you wanna know all these? Read the following carefully to get answers for all these Before knowing to know what exactly it is, let us initially have a look at the evolution Evolution  of IoT: The evaluation of  Internet of Things platforms can be  explained below: Pre-internet: In the pre-internet, most of the human to human communication was through a fixed and mobile telephony. Dawn of Internet: The world was changed unexpectedly with the origin of the internet. We  people can able to get the desired information within a button click. What is IoT? The Internet of Things(IoT) is a network of interrelated computing devices, mechanical and digital machines. These devices contains unique identifiers that transfer the data over the network. It does the work without the human-human interaction (or) human-machine interaction. In other words, it is also defined as a connection on the (or) device and can connect WIFI. This platform has its presence in many places in our daily life. Through this platform, we people can connect kitchen appliances, cars, thermostats, to the embedded devices via the internet. Through low-cost computing, cloud, big data, analytics, and mobile technologies physical things can share and collect the data with minimal human intervention. Moreover, digital systems were capable of record, monitor, and adjust each interaction between the connected things. Do you wanna know more about this platform? Get it at IoT Online Training  from  live experts Till now, we people have got basic information on the Internet of Things, let us have a look at its architecture IoT Architecture: IoT is not just internet-connected consumer devices. It is a technology that builds systems capable of sensing and respond to stimuli from the real world without human intervention. So we need to develop a process flow for a definite framework over which IoT solution is built. The platform architecture generally comprises of 4 stages:   Stage-1 (sensors/actuators): A thing in the context of the Internet of Things should be equipped with sensors and actuators and thus gives the ability to emit, accept, and process signals. Stage-2 (Data Acquisition System): The data from the sensors start in an analogue form that needs to be aggregated and converted into digital streams for further processing, Here the data acquisition systems perform these aggregations, and the conversation functions Stage-3(Edge Analytics): Once the Internet of Things data has digitized and aggregated, it may require further processing before it enters the data center. Here the place, where the edge analytics comes into the picture. Stage-4(Cloud Analytics): Data that needs more in-depth processing gets forwarded to physical data centers (or) the cloud-based systems How does IOT work? The ecosystem of the Internet of things(IoT) comprises the internet-enabled smart devices like sensors, communication hardware (or) processors to gather, send, and act on the data acquired from the different environments. The data connected by the IoT devices is shared by connecting to other edge devices (or) an IoT gateway. Here the collected data can be analyzed locally (or) sent to the cloud for analysis purposes. Besides IoT devices were capable of communicating with other related devices and act as data exchange with another. Here the devices do their job without human intervention. Moreover, people who own the devices can interact with the devices for setting up and give instructions to access the data. Examples of IoT: a)A “thing” on the Internet of Things (IoT) can be a car with in-built sensors to alert the driver about the low pressure on tires b)Intelligent Sensors, UID, and transponders that can be accommodated in machines such as coffee machines, cell phones, and home appliances like lamps, washing machines, wearable devices. Likewise, there are multiple examples of the Internet of Things, let us discuss some with the application of this platform. Applications of IoT: a)Disaster Management : IoT can be used o accumulate the data related to the specific location using remote monitoring tools and platform analytics. Moreover, with the application of the Internet of Things, we can also get the early warning of the disaster. b)Health Care: IoT may have a major impact when it comes to remote health monitoring. Using this platform, we can send the patient vitals to the doctor. c)Farming: With IoT, we can automate the task of irrigation. Besides a set of sensors such as light, humidity, the temperature  can be used to monitor the field conditions d)Smart Energy Management: With Smart grids, energy distribution can be easily optimized. These grids also keep collecting the real-time data by distributing the  electricity efficiently and also reduce the outages e)Pollution Control : The IoT platform helps us to continuously monitor the air quality as well as the water quality. Here the data will be sent to the cloud for further analysis. Using the analytics report we can take the proper action for pollution control. f) Manufacturing: Manufacturers can gain a competitive advantage by using the production line monitoring to enable the proactive maintenance of equipment when the sensors predict the upcoming failure. Besides  the devices were capable of measuring the production output is compromised. Moreover, with sensor alerts, manufacturers can quickly check equipment for accuracy (or) remove it from the production until it is repaired. Hence through IoT, companies can reduce the operating costs, get better uptime, and thus improve asset performance management. Hence likewise, there is much application of the Internet of Things that we were habituated to use in our daily life. You people can get more examples of the Internet of Things and its applications by live industry experts at the IoT Online Course. Final Words: I hope you people have gained enough stuff regarding the need and utilization of IoT in industry. In the upcoming posts of this blog, I'll be sharing the details of the application of each area with real-time use cases. Meanwhile, have a look at our IoT Interview Questions and get placed in a reputed firm.

What is Angular JS?

The website is the basic need for marketers to reach a mass number of people. With the high availability of content management systems, website development has become a cakewalk in the IT World. But we cannot except the best website unless you develop using best platform. So what does it mean the best website? A website is considered as the best website if it is user-friendly ( Compatible to all devices and loads in an optimal time across various platforms). So here developing a website is an ordinary thing. But developing a user-friendly application is a challenging thing that is essential in today's world. So how to develop an intuitive web application. Which platform suits best in developing an intuitive application? Then without the second thought most of the developers vote for AngularJS.  So, But before know about AngularJs, let us have an initial look at What is a Framework? A framework is a collection of code libraries where some functions were predefined. By the utilization of this framework, developers can easily develop lightweight applications. Moreover, the developer can concentrate on actual logic rather than struggling with the code dependencies. In simple words, the utilization of these predefined codes makes the website development in a short period. Hence now, let's move into the actual concept What is Angular JS? Angular JS is an open-source web application framework developed in 2009. This was developed by Misko Hervy and Adam Abrons. This framework was now maintained by Google. This framework architecture depends on the Model View Controller (MVC) framework that is similar to the Java Script Framework.  Moreover, this framework suits best in developing single-page applications. It is a continuously growing and expanding framework in providing better ways of application development. Moreover, this platform is capable of changing from static HTML to Dynamic HTML. Besides, it provides features like dynamic building, dependency injection, and also the code rewriting. Moreover, Angular JS is different from Angular framework. And AngularJS is also capable of extending HTML attributes with directives. Since, we people have got an basic idea regarding AngularJS, let us have a look at its architecture. Get practical exposure on AngularJS with practical use cases at AngularJs Online Training AngularJS Architecture: As mentioned above, Angular framework works on MVC architecture. So let us have a look at its architecture. MVC Architecture: An architecture is basically a pattern used to develop an application. This Angular JS Architecture usually consists of three components. They are : Model: It is responsible to manage the application data. It responds to the instruction from the view and the instructions from the control to update it self. View: It is responsible for displaying the application data. It also specifies the data in a triggered format by the controller to present the data. Since its an script based template such as JSP, ASP, PHP, it is easy to integrate with the AJAX technology. Controller: This component is responsible for connecting the model and the view component.It responds to the user inputs and perform data interactions on the data model objects. This architecture is very poplar, because. it isolates the application logic from the user interface and supports separation of concerns. Besides, whenever we talk about the MVC architecture, we have to split our application into three components and then write the code to connect them. But when comes to angular JS, all we need to is to split the application into MVC and the framework takes care of the rest. Hence this framework is capable of saving the lot of time and allows to finish the job with less code. Whenever the controller receives the input, it validates the input and performs the business operations that modify the data model state. What are the AngularJS Components? AngularJS consist of several components. Let us discuss some of them. They are: a)Data Binding: Data binding in AngularJs is a two-way process i.e the view layer of MVC architecture is the exact copy of the Model layer. Hence, there is no necessity to write the special code to bind the data to the HTML Controls. Usually in MVC architectures, we need to continuously update the view layer and model layer to remain in sync with each other. In AngularJs we can say that model and view layer synchronized each other. So when ever the data in the model changes, the view layer reflects the change and vice-versa. All this happens in angular is immediately and automatically. It makes sure that model and view is updated all the times. b)Templates: One of the major use of this application framework is make use of templates. Usually what happens in AngularJs, is templates were passed by browser into DOM. Here the DOM becomes the input of the Angular JS Compiler. The Angular JS then travels the DOM templates for rendering the instructions called Directives. The other siblings of Angular JS Work differently. These make use of HTML String, where as AngularJS does not manipulate the template strings. With DOM, we have the privilege to extend directive vocabulary (or) even abstract them into reusable components. c)Dependency Injection: It is a software design pattern work on Inversion of the Control. Here the term Inversion control refers to the objects that does not create the other objects. Hence , they used to get the objects from an external source. Moreover, the primary object is not capable of dependent object, so an external source creates a dependent object and gives to the source object for further usage. Hence on the basis of dependency injection, we can create all the information database and can get into the model class. In AngularJS, dependencies were injected using “injectable factory method”(or) constructor function. d) Scope: It is an built-in object in AngularJs which contains application data and models. Here the $scope is responsible to transfer the data from controller to the view and vice-versa. Besides, we can create properties to the $scope object inside the controller function and assign a value to it. e)Controller: A controller is a java script constructor function that contains the attributes/properties and functions in AngularJS that is responsible to increase the Angular JS Scope. And each controller accepts the scope as a parameter that refers to the application that needs to handle. Hence likewise, there are many other components of AngularJs. You people can acquire practical knowledge of AngularJS components by live experts with practical use cases through AngularJS Online Course. Final Words: With this, I hope you people have got an basic overview of Angular and its components. In the upcoming post of this blog, Ill be sharing you the details of working of various Angular JS components in details and application in IT industry. Meanwhile Have a glance at our AngularJS Interview Questions and crack the interview.

What is Google Cloud Platform?

It seems difficult to sustain life in the IT industry without using the most common search engine like Google. This vendor is not only limited its services to the search engine but also has its roots in the area of cloud computing. Many IT companies today were utilizing this cloud computing for the smooth running of the business. According to recent statistics, 49% of IT professionals use the Google Cloud platform as the primary resource of computation. And the next followers were Microsoft Azure and Amazon web services with 48 % and 42 % of IT Professionals respectively. So with this, we can say Google Cloud platform stood at the top of cloud computing services. Hence, a question comes to your mind, “Even though Amazon, Azure, and other cloud computing services perform the same, why this cloud computing platform stood top?” If “YES”, continue your reading with Why do we need Cloud Computing? People prefer to utilize cloud computing services to scale the resources as per the demand at an affordable price. Moreover, we people opt for these cloud services to reduce infrastructure services. These kinds of services suit best for starters. The specialty of the cloud computing platform is, it provides a space for individuals as well as the enterprises to build and run the software. Google is one of the topmost vendors in providing cloud computing services. Hence without wasting much time, let us have a quick discussion on What is Google  Cloud Computing? Google Cloud Platform is a suite of google public cloud computing services. This platform includes a range of hosted services for compute, storage, application development that runs on the Google hardware. Besides, these services can be easily accessed by software developers, cloud administrators, and other IT Professionals through a public (or) a dedicated Internet connection. This vendor provides excellent services to the people through the pay-as-you-go model. Besides this cloud computing platform makes use of internet remote servers to store, manage as well as process the data instead of local server  (or) the personal computer. Know more on GCP by live experts with practical use cases at Google Cloud Online Training Where do we can find this service? Google has its data centers at several places across the globe. Some of them were North America, South America, Europe, Asia, and Australia. Furthermore, these locations were further divided into regions and zones. These were the data center locations as of today. And this vendor is in a process of establishing the data centers in some more locations across the globe. Hence with this, the user can select the nearest region to get the unstoppable service with high availability of the service. Whenever you launch an application (or) service,  on the google cloud platform, google keeps track of all the resource utilization.

Hadoop Cluster Interview Questions

Hadoop Cluster Interview  Questions Q.Explain About The Hadoop-core Configuration Files? Ans: Hadoop core is specified by two resources. It is configured by two well written xml files which are loaded from the classpath: Hadoop-default.xml- Read-only defaults for Hadoop, suitable for a single machine instance. Hadoop-site.xml- It specifies the site configuration for Hadoop distribution. The cluster specific information is also provided by the Hadoop administrator. Q.Explain In Brief The Three Modes In Which Hadoop Can Be Run? Ans : The three modes in which Hadoop can be run are: Standalone (local) mode- No Hadoop daemons running, everything runs on a single Java Virtual machine only. Pseudo-distributed mode- Daemons run on the local machine, thereby simulating a cluster on a smaller scale. Fully distributed mode- Runs on a cluster of machines. Q.Explain What Are The Features Of Standalone (local) Mode? Ans : In stand-alone or local mode there are no Hadoop daemons running,  and everything runs on a single Java process. Hence, we don't get the benefit of distributing the code across a cluster of machines. Since, it has no DFS, it utilizes the local file system. This mode is suitable only for running MapReduce programs by developers during various stages of development. Its the best environment for learning and good for debugging purposes. Q.What Are The Features Of Fully Distributed Mode? Ans:In Fully Distributed mode, the clusters range from a few nodes to 'n' number of nodes. It is used in production environments, where we have thousands of machines in the Hadoop cluster. The daemons of Hadoop run on these clusters. We have to configure separate masters and separate slaves in this distribution, the implementation of which is quite complex. In this configuration, Namenode and Datanode runs on different hosts and there are nodes on which task tracker runs. The root of the distribution is referred as HADOOP_HOME. Q.Explain What Are The Main Features Of Pseudo Mode? Ans : In Pseudo-distributed mode, each Hadoop daemon runs in a separate Java process, as such it simulates a cluster though on a small scale. This mode is used both for development and QA environments. Here, we need to do the configuration changes. Q.What Are The Hadoop Configuration Files At Present? Ans : There are 3 configuration files in Hadoop: conf/core-site.xml: fs.default.name hdfs: //localhost:9000 conf/hdfs-site.xml: dfs.replication 1 conf/mapred-site.xml: mapred.job.tracker local host: 9001 Q.Can You Name Some Companies That Are Using Hadoop? Ans : Numerous companies are using Hadoop, from large Software Companies, MNCs to small organizations. Yahoo is the top contributor with many open source Hadoop Softwares and frameworks. Social Media Companies like Facebook and Twitter have been using for a long time now for storing their mammoth data. Apart from that Netflix, IBM, Adobe and e-commerce websites like Amazon and eBay are also using multiple Hadoop technologies. Q.Which Is The Directory Where Hadoop Is Installed? Ans : Cloudera and Apache have the same directory structure. Hadoop is installed in cd /usr/lib/hadoop-0.20/. Q.What Are The Port Numbers Of Name Node, Job Tracker And Task Tracker? Ans : The port number for Namenode is ’70′, for job tracker is ’30′ and for task tracker is ’60′. Q.Tell Us What Is A Spill Factor With Respect To The Ram? Ans : Spill factor is the size after which your files move to the temp file. Hadoop-temp directory is used for this. Default value for io.sort.spill.percent is 0.80. A value less than 0.5 is not recommended. Q.Is Fs.mapr.working.for A Single Directory? Ans : Yes, fs.mapr.working.dir it is just one directory. Q.Which Are The Three Main Hdfs-site.xml Properties? Ans : The three main hdfs-site.xml properties are: name.dir which gives you the location on which metadata will be stored and where DFS is located – on disk or onto the remote. data.dir which gives you the location where the data is going to be stored. checkpoint.dir which is for secondary Namenode. Q.How To Come Out Of The Insert Mode? Ans : To come out of the insert mode, press ESC, Type: q (if you have not written anything) OR Type: wq (if you have written anything in the file) and then press ENTER. Q.Tell Us What Cloudera Is And Why It Is Used In Big Data? Ans : Cloudera is the leading Hadoop distribution vendor on the Big Data market, its termed as the next-generation data management software that is required for business critical data challenges that includes access, storage, management, business analytics, systems security, and search. Q.We Are Using Ubuntu Operating System With Cloudera, But From Where We Can Download Hadoop Or Does It Come By Default With Ubuntu? Ans : This is a default configuration of Hadoop that you have to download from Cloudera or from eureka’s Dropbox and the run it on your systems. You can also proceed with your own configuration but you need a Linux box, be it Ubuntu or Red hat. There are installations steps present at the Cloudera location or in Eureka’s Drop box. You can go either ways. Q.What Is The Main Function Of The ‘jps’ Command? Ans : The jps’ command checks whether the Datanode, Namenode, tasktracker, jobtracker, and other components are working or not in Hadoop. One thing to remember is that if you have started Hadoop services with sudo then you need to run JPS with sudo privileges else the status will be not shown. Q.How Can I Restart Namenode? Ans : Click on stop-all.sh and then click on start-all.sh OR Write sudo hdfs (press enter), su-hdfs (press enter), /etc/init.d/ha (press enter) and then /etc/init.d/hadoop-0.20-namenode start (press enter). Q.How Can We Check Whether Namenode Is Working Or Not? Ans : To check whether Namenode is working or not, use the command /etc/init.d/hadoop- 0.20-namenode status or as simple as jps’. Q.What Is "fsck" And What Is Its Use? Ans : "fsck" is File System Check. FSCK is used to check the health of a Hadoop Filesystem. It generates a summarized report of the overall health of the filesystem. Usage:  hadoop fsck / Q.At Times You Get A ‘connection Refused Java Exception’ When You Run The File System Check Command Hadoop Fsck /? Ans : The most possible reason is that the Namenode is not working on your VM. Q.What Is The Use Of The Command Mapred.job.tracker? Ans : The command mapred.job.tracker is used by the Job Tracker to list out which host and port that the MapReduce job tracker runs at. If it is "local", then jobs are run in-process as a single map and reduce task. Q.What Does /etc /init.d Do? Ans : /etc /init.d specifies where daemons (services) are placed or to see the status of these daemons. It is very LINUX specific, and nothing to do with Hadoop. Q.How Can We Look For The Namenode In The Browser? Ans : If you have to look for Namenode in the browser, you don’t have to give localhost: 8021, the port number to look for Namenode in the browser is 50070. Q.How To Change From Su To Cloudera? Ans : To change from SU to Cloudera just type exit. Q.Which Files Are Used By The Startup And Shutdown Commands? Ans : Slaves and Masters are used by the startup and the shutdown commands. Q.What Do Masters And Slaves Consist Of? Ans : Masters contain a list of hosts, one per line, that are to host secondary namenode servers. Slaves consist of a list of hosts, one per line, that host datanode and task tracker servers. Q.What Is The Function Of Hadoop-env.sh? Where Is It Present? Ans : This file contains some environment variable settings used by Hadoop; it provides the environment for Hadoop to run. The path of JAVA_HOME is set here for it to run properly. Hadoop-env.sh file is present in the conf/hadoop-env.sh location. You can also create your own custom configuration file conf/hadoop-user-env.sh, which will allow you to override the default Hadoop settings. Q.Can We Have Multiple Entries In The Master Files? Ans : Yes, we can have multiple entries in the Master files. Q.In Hadoop_pid_dir, What Does Pid Stands For? Ans : PID stands for ‘Process ID’. Q.What Does Hadoop-metrics? Properties File Do? Ans : Hadoop-metrics Properties is used for ‘Reporting‘purposes. It controls the reporting for hadoop. The default status is ‘not to report‘. Q.What Are The Network Requirements For Hadoop? Ans : The Hadoop core uses Shell (SSH) to launch the server processes on the slave nodes. It requires password-less SSH connection between the master and all the slaves and the Secondary machines. Q.Why Do We Need A Password-less Ssh In Fully Distributed Environment? Ans : We need a password-less SSH in a Fully-Distributed environment because when the cluster is LIVE and running in Fully Distributed environment, the communication is too frequent. The job tracker should be able to send a task to task tracker quickly. Q.What Will Happen If A Namenode Has No Data? Ans : If a Namenode has no data it cannot be considered as a Namenode. In practical terms, Namenode needs to have some data. Q.What Happens To Job Tracker When Namenode Is Down? Ans : Namenode is the main point which keeps all the metadata, keep tracks of failure of datanode with the help of heart beats. As such when a namenode is down, your cluster will be completely down, because Namenode is the single point of failure in a Hadoop Installation. Q.Explain What Do You Mean By Formatting Of The Dfs? Ans : Like we do in Windows, DFS is formatted for proper structuring of data. It is not usually recommended to do as it format the Namenode too in the process, which is not desired. Q.We Use Unix Variants For Hadoop. Can We Use Microsoft Windows For The Same? Ans : In practicality, Ubuntu and Red Hat Linux are the best Operating Systems for Hadoop. On the other hand, Windows can be used but it is not used frequently for installing Hadoop as there are many support problems related to it. The frequency of crashes and the subsequent restarts makes it unattractive. As such, Windows is not recommended as a preferred environment for Hadoop Installation, though users can give it a try for learning purposes in the initial stage. Q.Which One Decides The Input Split - Hdfs Client Or Namenode? Ans : The HDFS Client does not decide. It is already specified in one of the configurations through which input split is already configured. Q.Let’s Take A Scenario, Let’s Say We Have Already Cloudera In A Cluster, Now If We Want To Form A Cluster On Ubuntu Can We Do It. Explain In Brief? Ans : Yes, we can definitely do it. We have all the useful installation steps for creating a new cluster. The only thing that needs to be done is to uninstall the present cluster and install the new cluster in the targeted environment. Q.Can You Tell Me If We Can Create A Hadoop Cluster From Scratch? Ans : Yes, we can definitely do that.  Once we become familiar with the Apache Hadoop environment, we can create a cluster from scratch. Q.Explain The Significance Of Ssh? What Is The Port On Which Port Does Ssh Work? Why Do We Need Password In Ssh Local Host? Ans : SSH is a secure shell communication, is a secure protocol and the most common way of administering remote servers safely, relatively very simple and inexpensive to implement. A single SSH connection can host multiple channels and hence can transfer data in both directions. SSH works on Port No. 22, and it is the default port number. However, it can be configured to point to a new port number, but its not recommended. In local host, password is required in SSH for security and in a situation where password less communication is not set. Q.What Is Ssh? Explain In Detail About Ssh Communication Between Masters And The Slaves? Ans : Secure Socket Shell or SSH is a password-less secure communication that provides administrators with a secure way to access a remote computer and data packets are sent across the slave. This network protocol also has some format into which data is sent across. SSH communication is not only between masters and slaves but also between two hosts in a network.  SSH appeared in 1995 with the introduction of SSH - 1. Now SSH 2 is in use, with the vulnerabilities coming to the fore when Edward Snowden leaked information by decrypting some SSH traffic. Q.Can You Tell Is What Will Happen To A Namenode, When Job Tracker Is Not Up And Running? Ans : When the job tracker is down, it will not be in functional mode, all running jobs will be halted because it is a single point of failure. Your whole cluster will be down but still Namenode will be present. As such the cluster will still be accessible if Namenode is working, even if the job tracker is not up and running. But you cannot run your Hadoop job. keywords: hadoop cluster interviewquestions,interview questions on hadoop cluster,hadoop cluster interview questions and answers,hadoop cluster interview questions pdf,hadoop cluster interview questions and answers pdf, hadoop cluster  interview questions,interview questions on hadoop,hadoop cluster  interview questions and answers,hadoop interview questions pdf,hadoop interview questions and answers pdf, hadoop interview questions

Go Language interview Questions

Q.What Is Go? Ans: Go is a general-purpose language designed with systems programming in mind.It was initially developed at Google in year 2007 by Robert Griesemer, Rob Pike, and Ken Thompson. It is strongly and statically typed, provides inbuilt support for garbage collection and supports concurrent programming. Programs are constructed using packages, for efficient management of dependencies. Go programming implementations use a traditional compile and link model to generate executable binaries. Q.What Are The Benefits Of Using Go Programming? Ans: Support for environment adopting patterns similar to dynamic languages. For example type inference (x := 0 is valid declaration of a variable x of type int). Compilation time is fast. InBuilt concurrency support: light-weight processes (via goroutines), channels, select statement. Conciseness, Simplicity, and Safety. Support for Interfaces and Type embdding. Production of statically linked native binaries without external dependencies. Q.Does Go Support Type Inheritance? Ans: No support for type inheritance. Q.Does Go Support Operator Overloading? Ans: No support for operator overloading. Q.Does Go Support Method Overloading? Ans: No support for method overloading. Q.Does Go Support Pointer Arithmetics? Ans: No support for pointer arithmetic. Q.Does Go Support Generic Programming? Ans: No support for generic programming. Q.Is Go A Case Sensitive Language? Ans: Yes! Go is a case sensitive programming language. Q.What Is Static Type Declaration Of A Variable In Go? Ans: Static type variable declaration provides assurance to the compiler that there is one variable existing with the given type and name so that compiler proceed for further compilation without needing complete detail about the variable. A variable declaration has its meaning at the time of compilation only, compiler needs actual variable declaration at the time of linking of the program. Q.What Is Dynamic Type Declaration Of A Variable In Go? Ans: A dynamic type variable declaration requires compiler to interpret the type of variable based on value passed to it. Compiler don't need a variable to have type statically as a necessary requirement. Q.Can You Declared Multiple Types Of Variables In Single Declaration In Go? Ans: Yes Variables of different types can be declared in one go using type inference. var a, b, c = 3, 4, "foo" Q.How To Print Type Of A Variable In Go? Ans: Following code prints the type of a variable − var a, b, c = 3, 4, "foo" fmt.Printf("a is of type %Tn", a) Q.What Is A Pointer? Ans: It's a pointer variable which can hold the address of a variable. For example − var x = 5 var p *int p = &x fmt.Printf("x = %d", *p) Here x can be accessed by *p. Q.What Is The Purpose Of Break Statement? Ans: Break terminates the for loop or switch statement and transfers execution to the statement immediately following the for loop or switch. Q.What Is The Purpose Of Continue Statement? Ans: Continue causes the loop to skip the remainder of its body and immediately retest its condition prior to reiterating. Q.What Is The Purpose Of Goto Statement? Ans: goto transfers control to the labeled statement. Q.Explain The Syntax For 'for' Loop? Ans: The syntax of a for loop in Go programming language is − for { statement(s); } Here is the flow of control in a for loop − if condition is available, then for loop executes as long as condition is true. if for clause that is ( init; condition; increment ) is present then The init step is executed first, and only once. This step allows you to declare and initialize any loop control variables. You are not required to put a statement here, as long as a semicolon appears. Next, the condition is evaluated. If it is true, the body of the loop is executed. If it is false, the body of the loop does not execute and flow of control jumps to the next statement just after the for loop. After the body of the for loop executes, the flow of control jumps back up to the increment statement. This statement allows you to update any loop control variables. This statement can be left blank, as long as a semicolon appears after the condition. The condition is now evaluated again. If it is true, the loop executes and the process repeats itself (body of loop, then increment step, and then again condition). After the condition becomes false, the for loop terminates. if range is available, then for loop executes for each item in the range. Q.Explain The Syntax To Create A Function In Go? Ans: The general form of a function definition in Go programming language is as follows − func function_name( ) { body of the function } A function definition in Go programming language consists of a function header and a function body. Here are all the parts of a function − func func starts the declaration of a function. Function Name − This is the actual name of the function. The function name and the parameter list together constitute the function signature. Parameters − A parameter is like a placeholder. When a function is invoked, you pass a value to the parameter. This value is referred to as actual parameter or argument. The parameter list refers to the type, order, and number of the parameters of a function. Parameters are optional; that is, a function may contain no parameters. Return Type − A function may return a list of values. The return_types is the list of data types of the values the function returns. Some functions perform the desired operations without returning a value. In this case, the return_type is the not required. Function Body − The function body contains a collection of statements that define what the function does. Q.Can You Return Multiple Values From A Function? Ans: A Go function can return multiple values. For example − package main import "fmt" func swap(x, y string) (string, string) { return y, x } func main() { a, b := swap("Mahesh", "Kumar") fmt.Println(a, b) } Q.In How Many Ways You Can Pass Parameters To A Method? Ans: While calling a function, there are two ways that arguments can be passed to a function: Call by value: This method copies the actual value of an argument into the formal parameter of the function. In this case, changes made to the parameter inside the function have no effect on the argument. Call by reference:This method copies the address of an argument into the formal parameter. Inside the function, the address is used to access the actual argument used in the call. This means that changes made to the parameter affect the argument. Q.What Is The Default Way Of Passing Parameters To A Function? Ans: By default, Go uses call by value to pass arguments. In general, this means that code within a function cannot alter the arguments used to call the function while calling max() function used the same method. Q.What Do You Mean By Function As Value In Go? Ans: Go programming language provides flexibility to create functions on the fly and use them as values. We can set a variable with a function definition and use it as parameter to a function. Q.What Are The Function Closures? Ans: Functions closure are anonymous functions and can be used in dynamic programming. Q.What Are Methods In Go? Ans: Go programming language supports special types of functions called methods. In method declaration syntax, a "receiver" is present to represent the container of the function. This receiver can be used to call function using "." operator. Q.What Is Default Value Of A Local Variable In Go? Ans: A local variable has default value as it corresponding 0 value. Q.What Is Default Value Of A Global Variable In Go? Ans: A global variable has default value as it corresponding 0 value. Q.What Is Default Value Of A Pointer Variable In Go? Ans: Pointer is initialized to nil. Q.Explain The Purpose Of The Function Printf()? Ans: Prints the formatted output. Q.What Is Lvalue And Rvalue? Ans: The expression appearing on right side of the assignment operator is called as rvalue. Rvalue is assigned to lvalue, which appears on left side of the assignment operator. The lvalue should designate to a variable not a constant. Q.What Is The Difference Between Actual And Formal Parameters? Ans: The parameters sent to the function at calling end are called as actual parameters while at the receiving of the function definition called as formal parameters. Q.What Is The Difference Between Variable Declaration And Variable Definition? Ans: Declaration associates type to the variable whereas definition gives the value to the variable. Q.Explain Modular Programming? Ans: Dividing the program in to sub programs (modules/function) to achieve the given task is modular approach. More generic functions definition gives the ability to re-use the functions, such as built-in library functions. Q.What Is A Token? Ans: A Go program consists of various tokens and a token is either a keyword, an identifier, a constant, a string literal, or a symbol. Q.Which Key Word Is Used To Perform Unconditional Branching? Ans: goto Q.What Is An Array? Ans: Array is collection of similar data items under a common name. Q.What Is A Nil Pointers In Go? Ans: Go compiler assign a Nil value to a pointer variable in case you do not have exact address to be assigned. This is done at the time of variable declaration. A pointer that is assigned nil is called a nil pointer. The nil pointer is a constant with a value of zero defined in several standard libraries. Q.What Is A Pointer On Pointer? Ans: It's a pointer variable which can hold the address of another pointer variable. It de-refers twice to point to the data held by the designated pointer variable. var a int var ptr *int var pptr **int a = 3000 ptr = &a pptr = &ptr fmt.Printf("Value available at **pptr = %dn", **pptr) Therefore 'a' can be accessed by **pptr. Q.What Is Structure In Go? Ans: Structure is another user defined data type available in Go programming, which allows you to combine data items of different kinds. Q.How To Define A Structure In Go? Ans: To define a structure, you must use type and struct statements. The struct statement defines a new data type, with more than one member for your program. type statement binds a name with the type which is struct in our case. The format of the struct statement is this − type struct_variable_type struct { member definition; member definition; ... member definition; } Q.What Is Slice In Go? Ans: Go Slice is an abstraction over Go Array. As Go Array allows you to define type of variables that can hold several data items of the same kind but it do not provide any inbuilt method to increase size of it dynamically or get a sub-array of its own. Slices covers this limitation. It provides many utility functions required on Array and is widely used in Go programming. Q.How To Define A Slice In Go? Ans: To define a slice, you can declare it as an array without specifying size or use make function to create the one. var numbers int /* a slice of unspecified size */ /* numbers == int{0,0,0,0,0}*/ numbers = make(int,5,5) /* a slice of length 5 and capacity 5*/ Q.How To Get The Count Of Elements Present In A Slice? Ans: len() function returns the elements presents in the slice. Q.What Is The Difference Between Len() And Cap() Functions Of Slice In Go? Ans: len() function returns the elements presents in the slice where cap() function returns the capacity of slice as how many elements it can be accomodate. Q.How To Get A Sub-slice Of A Slice? Ans: Slice allows lower-bound and upper bound to be specified to get the subslice of it using. Q.What Is Range In Go? Ans: The range keyword is used in for loop to iterate over items of an array, slice, channel or map. With array and slices, it returns the index of the item as integer. With maps, it returns the key of the next key-value pair. Q.What Are Maps In Go? Ans: Go provides another important data type map which maps unique keys to values. A key is an object that you use to retrieve a value at a later date. Given a key and a value, you can strore the value in a Map object. After value is stored, you can retrieve it by using its key. Q.How To Create A Map In Go? Ans: You must use make function to create a map. /* declare a variable, by default map will be nil*/ var map_variable mapvalue_data_type /* define the map as nil map can not be assigned any value*/ map_variable = make(mapvalue_data_type) Q.How To Delete An Entry From A Map In Go? Ans: delete() function is used to delete an entry from the map. It requires map and corresponding key which is to be deleted. Q.What Is Type Casting In Go? Ans: Type casting is a way to convert a variable from one data type to another data type. For example, if you want to store a long value into a simple integer then you can type cast long to int. You can convert values from one type to another using the cast operator as following: type_name(expression) Q.What Are Interfaces In Go? Ans: Go programming provides another data type called interfaces which represents a set of method signatures. struct data type implements these interfaces to have method definitions for the method signature of the interfaces.

Chef (Software) Interview Questions

Chef Interview Questions and Answers  Q.What Is A Resource? Ans: A resource represents a piece of infrastructure and its desired state, such as a package that should be installed, a service that should be running, or a file that should be generated. Q.What Is A Recipe? Ans: A recipe is a collection of resources that describes a particular configuration or policy. A recipe describes everything that is required to configure part of a system. Recipes do things such as: Install and configure software components. Manage files. Deploy applications. Execute other recipes. Q.What Happens When You Don’t Specify A Resource’s Action? Ans: When you don’t specify a resource’s action, Chef applies the default action. Q.Write A Service Resource That Stops And Then Disables The Httpd Service From Starting When The System Boots? Ans: Service ‘httpd’ do Action End Q.How Does A Cookbook Differ From A Recipe? Ans: A recipe is a collection of resources, and typically configures a software package or some piece of infrastructure. A cookbook groups together recipes and other information in a way that is more manageable than having just recipes alone. For example, in this lesson you used a template resource to manage your HTML home page from an external file. The recipe stated the configuration policy for your web site, and the template file contained the data. You used a cookbook to package both parts up into a single unit that you can later deploy. Q.How Does Chef-apply Differ From Chef-client? Ans: Chef-apply apply a single recipe; chef-client applies a cookbook. For learning purposes, we had you start off with chef-apply because it helps you understand the basics quickly. In practice, chef-apply is useful when you want to quickly test something out. But for production purposes, you typically run chef-client to apply one or more cookbooks. Q.What’s The Run-list? Ans: The run-list lets you specify which recipes to run, and the order in which to run them. The run-list is important for when you have multiple cookbooks, and the order in which they run matters. Q.What Are The Two Ways To Set Up A Chef Server? Ans: Install an instance on your own infrastructure. Use hosted Chef. Q.What’s The Role Of The Starter Kit? Ans: The Starter Kit provides certificates and other files that enable you to securely communicate with the Chef server. Q.What Is A Node? Ans: A node represents a server and is typically a virtual machine, container instance, or physical server – basically any compute resource in your infrastructure that’s managed by Chef. Q.What Information Do You Need To In Order To Bootstrap? Ans: You need: Your node’s host name or public IP address. A user name and password you can log on to your node with. Alternatively, you can use key-based authentication instead of providing a user name and password. Q.What Happens During The Bootstrap Process? Ans: During the bootstrap process, the node downloads and installs chef-client, registers itself with the Chef server, and does an initial check in. During this check in, the node applies any cookbooks that are part of its run-list. Q.Which Of The Following Lets You Verify That Your Node Has Successfully Bootstrapped? Ans: The Chef management console. Knife node list Knife node show You can use all three of these methods. Q.What Is The Command You Use To Upload A Cookbook To The Chef Server? Ans: Knife cookbook upload. Q.How Do You Apply An Updated Cookbook To Your Node? Ans: We mentioned two ways. Run knife Ssh from your workstation. SSH directly into your server and run chef-client. You can also run chef-client as a daemon, or service, to check in with the Chef server on a regular interval, say every 15 or 30 minutes. Update your Apache cookbook to display your node’s host name, platform, total installed memory, and number of CPUs in addition to its FQDN on the home page. Update index.html.erb like this. hello from < /h1> – RAM CPUs Then upload your cookbook and run it on your node. Q. What Would You Set Your Cookbook’s Version To Once It’s Ready To Use In Production? Ans: According to Semantic Versioning, you should set your cookbook’s version number to 1.0.0 at the point it’s ready to use in production. Q. Create A Second Node And Apply The Awesome Customers Cookbook To It. How Long Does It Take? Ans: You already accomplished the majority of the tasks that you need. You wrote the awesome customers cookbook, uploaded it and its dependent cookbooks to the Chef server, applied the awesome customers cookbook to your node, and verified that everything’s working. All you need to do now is: Bring up a second Red Hat Enterprise Linux or Centos node. Copy your secret key file to your second node. Bootstrap your node the same way as before. Because you include the awesome customers cookbook in your run-list, your node will apply that cookbook during the bootstrap process. The result is a second node that’s configured identically to the first one. The process should take far less time because you already did most of the work. Now when you fix an issue or add a new feature, you’ll be able to deploy and verify your update much more quickly! Q. What’s The Value Of Local Development Using Test Kitchen? Ans: Local development with Test Kitchen: Enables you to use a variety of virtualization providers that create virtual machine or container instances locally on your workstation or in the cloud. Enables you to run your cookbooks on servers that resemble those that you use in production. Speeds up the development cycle by automatically provisioning and tearing down temporary instances, resolving cookbook dependencies, and applying your cookbooks to your instances.
