Hadoop Interview Questions

Hadoop technology is largely used by the web 2.0 companies like Google and Facebook as it is highly scalable open source data management system. Some of the branches of Hadoop are Hadoop architecture, Map Reduce, HDFS, YARN, pig, Hive, SPark, Oozie, Hbase, Squoop etc. Let me fetch the difficult questions from all these branches and help the learners to clear the interview with less effort. The data processing tools are located on the same server and the distributed file system on the cluster made the Hadoop as the fast and efficient system to process the terabytes of data.

  1. Explain the term Map Reduce?

To process the large data sets in the hadoop cluster the Map Reduce framework is used. There are two sets in the data process and they are the mapping of data and reduce process of the data which means filtering the data as per the query. Hadoop Training in Chennai teach about how to manage huge volume of data and analyze the huge volume of data.

  1. Explain the process of the Hadoop Map Reduce works?

Map Reduce count the words in each document and reduce the words or phase in to splits for the analysis. The map task is performed in the Map Reduce.

  1. Explain the term shuffling in Map Reduce?

The process of transferring the map outputs after the system performs the sort is called as shuffle. The system transfers the map outputs to the reducer as inputs in the Map Reduce. Big Data Training in Chennai aids for the advanced data analysis and this help to improve the profitability of the business.

  1. Define the term distributed Cache in Map Reduce Framework?

Distributed Cache is used to share some files from the nodes in the Hadoop Cluster and the file can be an executable jar files or simple properties file.

  1. Describe the actions followed by the Job tracker in Hadoop?

The Job tracker performs the actions like submitting the job to the job tracker from the client application, to determine the data location the job tracker communicates to the name mode, the task tracker nodes are located to near the data or with the available slots job tracker, the work is submitted by the job tracker to the chosen task tracker nodes, if there is failure in the task then the job tracker notify and decides what to do then, and the job tracker monitor the task tracker in the nodes.

  1. Mention what is the heartbeat in HDFS?

Data node and a name node pass signal and task tracker and job tracker also pass signal and this signal is called as the heart-beat of the HDFS. If there is any issue with the job tracker or the name node then the signal is not responded to the signal and then it is understood that there is some issues with the data node or task tracker.

  1. What is the purpose of using the Hadoop in the MapReduce job?

Combiners are used to increase the efficiency of the Map Reduce program, the data and the code can be reduced using the combiners. If the operation is cumulative and associative then reducer code is used as a combiner and it is also used to reduce the data before transferring. Big Data Course in Chennai help the employers to get high salary as it is the back bone of any business.

  1. Explain the scenarios in which the data node fails?

The data node fails when the tasks are re-scheduled in the node, the failure is detected from the jobtracker and the namenode, and the user data in the name node is replicated to another node.

  1. What are the two basic parameters of a mapper?

Longwritable and Text, Text and intWritable are the two parameters in a mapper.

  1. Describe the function of MApReduce partitioner?

The function of the MapReduce partitioner is to check the process of the key’s value goes to the reducer. These will distribute the map output evenly over the reducers. Big Data Course improves the job prospects to the freshers and experienced.

  1. Mention the difference between input split and the HDFS Block?

The HDFS block is the physical division of the data and the logical division of data is known as the input split of data.

  1. Describe the term textinformat in the Hadoop?

In testinformat the value is the content of the line, key is the byte offset of the line, and the text is the record in each line.

  1. Mention the configuration parameters which are needed to run the Mapreduce job?

Input format, output format, job’s input locations in the distributed file system, job’s output location in the distributed file system, class containing the map function, class containing the reduce function and the JAR file containing the mapper, reducer and driver classes are the configuration parameters in the MapReduce job.

  1. Describe the term WebDAV in Hadoop?

To access HDFS as a standard file system and expose the HDFS over WebDAV. HDFS file systems are mounted as file systems on most of the operating systems. WebDAV is a set of extensions to HTTP and it is used to support the editing and updating of the files. Big Data Training is the in-demand technology of this decade because of the wide of its componenets such as HDFS, YARN, Mapreduce, pig, hive, and sqoop etc.

  1. What is the function of the Squoop in hadoop?

To transform the data from MySQL or Oracle squoop is used. To export data from HDFS to RDMS and to import Data from RDMS to HDFS Squoop is used.

  1. Explain the function of a job tracker when scheduling a task?

To check whether the job tracker is active and functioning well the task tracker sends heartbeat messages to the job tracker. The number of available slots and this gives updation to the job tracker regarding the cluster work to be delegated.

  1. Describe the sequencefileinputformat in the hadoop?

Sequencefileinputformat is used to read the files in sequence and it pass the data from one mapreduce job to the other mapreduce job. It is a binary file format which is optimized for passing the data.

  1. Explain the function of the conf.setMapper class?

Hadoop Sample Resumes

Hadoop Industry updates

 What is new in Hadoop?

The industry standard hardware from Hadoop helps to store the data for the analysis of the data applied to the structured and unstructured data. To move the data the bulk load processing and streaming techniques are used. Apache squoop is used to move the data through bulk load process. Apache flume and Apache kafka is used to move the data through streaming. The data process options are fast and grouped as batch. The fast in memory is called as the Apache spark and the data processing as batch is called as Apache hive or Apache pig. Join the Hadoop Training in Chennai to know about the industrial updates and industrial demand for the hadoop technology. Cloudera and Apache impala have turneddata analysis to BI quality. It has compatibility with all leading BI tools and the high performance of the SQL help for the analysis of the patterns in the data.

Innovation from Santander

The latest innovation of Santander UK’s next generation is the data warehousing and steaming analytics to improve the customer experience. Apache kudu is used for the fast analytics. This is used for the operations like offloading workload from existing legacy systems, ask questions regarding the customer behavior and ask questions regarding the current status of the bank. With the help of Apache Kafka the data streams can be easily moved to online. Apache kudu vault is conforming the data events from the Hub, satellite and link structure of the Data Vault 2.0 methodology. The elastic event delivery platform is based on the scalaAkka and Apache Kafka for the data transformation. The fast data, timely decisions, reusable patterns and high speed are essential factors for the reusable platform and architecture.  The big community followers and high level products show the demand for the Big Data Training in Chennai. For the sake of financial security and enhance the customer satisfaction the Santander UK innovated the real time insight. The cluster used by the legacy systems requires the raw event streams that are canonical. This canonical event stream is redistributed to the other systems. The other systems like HDFS file system, Apache HBase or Apache kudu. This innovation was awarded as the data impact award finalist.

Hadoop 3

Hadoop 3 demand for the Java 8 and to work withhadoop3 java 7 is not helpful for the developers. The erasure encoding in HDFS will provide the fault tolerance and reduce the storage overhead. The smaller units in the sequential data are divided as bit, byte and block. Join the Big Data Course in Chennai and head the big team of data analysts in a reputed company with the help of the practical knowledge and the constant interest towards learning. These smaller units are saved in different disks in the hadoop. The compared with the HDFS replication the overhead cost of the Erasure coding is comparatively less. The factors like the storage, network and CPU decides the overheads of the erasure coding.Yarn 2 supports the flows or logical applications are supported by the notion of flows explicitly. The time line collector in the YARN separates the data and sent it to the resource manager timeline collector. The shell script rewrite is designed with new features like all the variables in one location which is called as, it is easy to start a daemon command, if pdsh is installed then ssh connections are used in the operations, without symlinkinghadoop is honoured now, the error messages are handled well by displaying it to the user.


The namenode extensions, client extensions, datanode extensions, and erasure coding policy forms the architecture of the HDFS erasure encoding. YARN timeline service v.2 is updated on the hadoop 3. The version 2 brings the scalable distributed writer architecture and a scalable backend storage. The queries from the YARN application are dedicated to the REST API. One collector is allocated to each YARN application and the APacheHBase is used as the primary backing storage. The Big Data Training is the best training to get placed in the big company and dream high with the top salary in the industry. The two major challenges are resolved with the updations in the YARN. The challenges are revolving around the scalability, reliability and usability. The scalability is reached with the seperation of the writes and the reads of data. The REST API help to resolve the problems from the queries and differentiate the queries. To process the large size data the HBase handles the response time very well.


The flows are explicit in the YARN version 2 and the storage system with the application master, node managers and resource managers are well planned. The data that belong to the application are collected in the application master, The resource manager collect the data with the time line collecter. Big Data Hadoop training with the expert trainers makes the subject still more interesting and provides in-depth knowledge in to the subject. To make the volume as reasonable the resource manager emits the YARN generic life cycle. The time line collector on the node which is running the application master with the node managers also collects and writes the data to the time line collector. The storage is backed up with the application master, node managers and the resource managers. The queries are handled by the REST API.

The new features in the shell script of the Hadoop also help to fix the bugs. The new aid for the collection of the variables in one location. The daemon is edited and it is easy to start a daemon in hadoop3. Daemon is used for the operations such as daemon stop, stop a daemon, and daemon status. The error messages are handled by the log and pid dirs on daemon start up. The unprotected errors are generally displayed to the user and it elminates the user satisafaction of using the system. So, the new hadoop 3 help for the elimination of error messages and efficient bug fixing. Join the Hadoop Training in Chennai and see the difference in the number of interviews you get. The right knowledge by the right time is important to get the success in the job.

The client jars in hadoop 3

The two depencies such as hadoop-client-api and hadoop-client-runtime artifacts are the two dependencies in the hadoop 3.The jars help to resolve the version conflicts in the hadoop. The version conflicts aids to the leakage in the classpath which is protected with the jars. It becomes easy for the hbase to talk to the hadoop cluster and there is not need for the depencies for the communication. The best training institutes extend their support till certification and provide the required help for the Big Data Certification in Chennai.

YARN contaniners and guaranteed containers help for the completion of the data analysis with out any failure. The distributed scheduler allow for the opportunistic container and it is implemented through the AMRMProtocol interceptor. These containers are allocated with the two properties such as the allocation and enabling the container. After adding the opportunistic contaner the web UI page contains different set of informations regarding the containers. The informations in the Web UI page are the total number of opportunistic containers on each node, the memory usage for the containers, The CPU virtual cores of the containers, the queued list of the containers in each node of the Hadoop. There are two ways to allocate the opportunistic container and they are centralized allocation and a distributed allocation. Gurantee containers are the capacoty scheduler where as opportunistic containers are used for execution of the application. If the management of the opportunistic containers are slow then it gives changes in the nodes. This condition leads to imbalance in the nodes. Big Data Training and Placement in Chennai help for the students till they get placed. The interview questions and the mock interviews are helpful to prepare yourself for the highly competitive job interviews.

Map reduce

For the shuffle intensive jobs the task level native optimization is a big boon. The map reduce is updated with this new feature. The nativemapoutputcollector will handle the mapper with sort, spill and IFile serialization. The native code is used to merge the code and handle the jobs effectively. Hadoop three help for the effective system maintenance. Big Data Training is suitable for the candidates with less interest in the programming and more interest in the analysis.

When handling the big volumes of data the fault tolerance is essential. The critical deployments demand for the fault tolerance. If one name node is active and the other 2 name nodes are passive then accordingly the fault in the name nodes are tolerable by the the architecture of the name nodes. Thus the name node with the changes and the ephemeral range help for the tolerance. Auto tuning and simplification of configuration makes the administration of the hadoop as a easy task. Join the Big Data Course in Chennai to set the regime to search the job rigorously.

Hadoop and Cloudera

The functions of the Cloudera or Hadoop or the Vsphere is to take care of the qualities such as maintenance mode, rack awareness, high availability, replication of data and the protection of data. Cloudera is the famous open source platform for the distribution. Know about the Best Big Data Training after a through analysis of the reviews and take demo class also as a deciding factor. For the virtual machines running on the top of the Vsphere the single user mode is used for the deployment process. There are so many services in the Hadoop like the HBase, Impala, and spark. For using all these services Cloudera manager is essential. To spin up these services the cloudera distribution helps for monitoring and managing the services. Join the Big Data and Hadoop Training in Chennai to get placed in the big companies and learn the technology from the tech savvy people.

Deployment of cloudera has a long process of deployment such as base VM template, Centos guest configuration, VMs required for the deployment, directories to be created for the cloudera manager VM, prepare the data nodes and name nodes. After this finally the Cloudera is deployed to use the multiple services of the Hadoop. Join the Big Data Hadoop Training and revalue your knowledge with the latest industrial updates. The coordination between Cloudera and Horton works leads to increase in the partnership with the public cloud vendors.

R interface in Impala

The R along with the popular package dplyr is used for the interative SQL queries. The new R package provides a grammar for the data manipulation and they are mutate(), select(), filter(), summarise() and arrange(). The SQL commands are directly executed on Impala using the implyr in R. It becomes easy to communicate with other self-service data science tools with the help of the implyr. RStudio gives updates on dplyr, DBI, dbplyr and odbc and the job of data scientists becomes easy.The Best Hadoop Training in Chennai treat each students as the pillars and community followers to grow the technology.

New features in H-base

For the vast usage and the best software eco system No SQL system is a suitable one. As it handles huge volume of data it is not possible to connect the data base with relational data. The no SQL data base supports for the ACID feature, the default implementations and the different columns per individual row in the same table is possible. The HDFS data nodes support for the smooth ditribution of the data accross the nodes. RDMS is suitable for the static data and for the dynamic data Hadoop is suitable. There are so many structures used to store the data like the binary trees, red black trees, heaps and vectors. There is a new model in the H-base which is called as LSM tree which has two sub divisions to operate the data. One is called as in memory tree and the other one is called as the disk store tree. The in-memory tree consists of the latest data and the disk store tree consists of the balance part of the data. Take the list of Hadoop Training Institute in Chennai and prepare your mind for the best training to learn the technology intensively.

Hadoop and Business

The usage of data analysis is huge in the business and the verge of the technology decides the business opportunities. Banking and Securities industries is prone to the challenges in the industry like the fraud detection, archival of audit, enterprise credit risk reporting, customer data transformation, and social analytics for trading. To track the fraud detections in the financial markets the network analytics and natural language processors are used widely which is operated by the Hadoop. In the media big data take part to make the content for the different types of audiences, recommend the content which is highly on demand, and show the performance of the content in different locality or different devices. In the health care sector the data from the app gives history about the usage of the medicine. Google maps are used to know about the health care information to track the spread of the chronic diseases. Big data is used to overcome the challenges in the manufacturing industry. The finance industry, health care industry and the streaming industry is booming to the top with the Hadoop technology.

Hadoop Tutorial


Execution of applications in Hadoop is done using the MapReduce algorithm the in which the data is processed in a parallel manner with others. In other words, Hadoop is used in order to develop various applications that will be able to perform complete statistical analysis over huge amounts of data. Thus, there are numerous uses of joining Hadoop Training in Chennai.

Modules of Hadoop

The various modules present in Hadoop are enlisted below:

HDFS: HDFS stands for Hadoop Distributed File System. According to the paper published by Google on the basis of HDFS states that files will be broken into small blocks and stored in nodes over distributed architecture.

It has numerous similarities with the existing distributed file systems. This is highly fault-tolerant and is designed to be used on low-cost hardware along with producing  high throughput access to the application data. Therefore, by learning in-depth knowledge become an expert in Big Data Training in Chennai.

Hadoop framework consists of the following two modules −

  • Hadoop Common − Java libraries and utilities that are required by other Hadoop modules.
  • Hadoop YARN – It is a framework for scheduling job along with cluster resource management.

Map Reduce: It is a framework that helps Java programs to do parallel computation on data with the usage of key value pair. This takes input data and converts into a data set that can be computed in the Key value pair. The output is consumed by reduce task followed by the desired output.

How does Hadoop work?

It is expensive to build large servers with heavy configurations in order to handle large scale processing. Hadoop enables execution of code across a cluster of computers and this includes the given core tasks that is performed by Hadoop −

  • Data is divided into directories and files. And Files are further divided into consistent sized blocks of 128M and 64M.
  • Files are then shared across various cluster nodes for the further process.
  • HDFS supervises the whole process.
  • Checking the execution of code successfully.
  • Blocks are copied for handling hardware failure.
  • Performing the sorting of data that takes place among map and reduce stages.
  • Sending the previously sorted data to specific computer.
  • Scripting the debugging logs for each job.

Hadoop Operation modes

After the downloading of Hadoop, begins the process of operating Hadoop cluster in any of the following modes supported by it:

  • Standalone Mode– By default, it is configured in this mode and can be executed as a single java process.
  • Pseudo Distributed Mode − Each Hadoop daemon like hdfs or yarn will be executed as a separate java process and this mode is useful for development stage.
  • Fully Distributed Mode– It is fully distributed with minimum two machines as a cluster..

Hadoop Instllation

The production environment for Hadoop is UNIX, still it can also be used in Windows by deploying Cygwin. Java 1.6 and later version is needed to run Map Reduce Programs. For the installation of Hadoop from tar ball on UNIX environment you need

  • Java Installation
  • SSH installation
  • Hadoop Installation
  • File Configuration
