A good understanding of Hadoop Architecture is required to leverage the power of Hadoop. Below are few important practical questions which can be asked to a Senior Experienced Hadoop Developer in an interview. I learned the answers to them during my CCHD (Cloudera Certified Haddop Developer) certification. I hope you will find them useful. This list primarily includes questions related to Hadoop Architecture, MapReduce, Hadoop API and Hadoop Distributed File System (HDFS). Hadoop is the most popular platform for big data analysis. The Hadoop ecosystem is huge and involves many supporting frameworks and tools to effectively run and manage it. This article focuses on the core of Hadoop concepts and its technique to handle enormous data. Hadoop is a huge ecosystem and referring to a good hadoop book is highly recommended. Below list of hadoop interview questions and answers that may prove useful for beginners and experts alike. These are common set of questions that you may face at big data job interview or a hadoop certification exam (like CCHD). What is a JobTracker in Hadoop? How many instances of JobTracker run on a Hadoop Cluster? JobTracker is the daemon service for submitting and tracking MapReduce jobs in Hadoop. There is only One Job Tracker process run on any hadoop cluster. Job Tracker runs on its own JVM process. In a typical production cluster its run on a separate machine. Each slave node is configured with job tracker node location. The JobTracker is single point of failure for the Hadoop MapReduce service. If it goes down, all running jobs are halted. JobTracker in Hadoop performs following actions(from Hadoop Wiki:) Client applications submit jobs to the Job tracker. The JobTracker talks to the NameNode to determine the location of the data The JobTracker locates TaskTracker nodes with available slots at or near the data The JobTracker submits the work to the chosen TaskTracker nodes. The TaskTracker nodes are monitored. If they do not submit heartbeat signals often enough, they are deemed to have failed and the work is scheduled on a different TaskTracker. A TaskTracker will notify the JobTracker when a task fails. The JobTracker decides what to do then: it may resubmit the job elsewhere, it may mark that specific record as something to avoid, and it may may even blacklist the TaskTracker as unreliable. When the work is completed, the JobTracker updates its status. Client applications can poll the JobTracker for information. How JobTracker schedules a task? The TaskTrackers send out heartbeat messages to the JobTracker, usually every few minutes, to reassure the JobTracker that it is still alive. These message also inform the JobTracker of the number of available slots, so the JobTracker can stay up to date with where in the cluster work can be delegated. When the JobTracker tries to find somewhere to schedule a task within the MapReduce operations, it first looks for an empty slot on the same server that hosts the DataNode containing the data, and if not, it looks for an empty slot on a machine in the same rack. What is a Task Tracker in Hadoop? How many instances of TaskTracker run on a Hadoop Cluster A TaskTracker is a slave node daemon in the cluster that accepts tasks (Map, Reduce and Shuffle operations) from a JobTracker. There is only One Task Tracker process run on any hadoop slave node. Task Tracker runs on its own JVM process. Every TaskTracker is configured with a set of slots, these indicate the number of tasks that it can accept. The TaskTracker starts a separate JVM processes to do the actual work (called as Task Instance) this is to ensure that process failure does not take down the task tracker. The TaskTracker monitors these task instances, capturing the output and exit codes. When the Task instances finish, successfully or not, the task tracker notifies the JobTracker. The TaskTrackers also send out heartbeat messages to the JobTracker, usually every few minutes, to reassure the JobTracker that it is still alive.

These message also inform the JobTracker of the number of available slots, so the JobTracker can stay up to date with where in the cluster work can be delegated. What is a Task instance in Hadoop? Where does it run? Task instances are the actual MapReduce jobs which are run on each slave node. The TaskTracker starts a separate JVM processes to do the actual work (called as Task Instance) this is to ensure that process failure does not take down the task tracker. Each Task Instance runs on its own JVM process. There can be multiple processes of task instance running on a slave node. This is based on the number of slots configured on task tracker. By default a new task instance JVM process is spawned for a task. How many Daemon processes run on a Hadoop system? Hadoop is comprised of five separate daemons. Each of these daemon run in its own JVM. Following 3 Daemons run on Master nodes NameNode - This daemon stores and maintains the metadata for HDFS. Secondary NameNode - Performs housekeeping functions for the NameNode. JobTracker - Manages MapReduce jobs, distributes individual tasks to machines running the Task Tracker. Following 2 Daemons run on each Slave nodes DataNode – Stores actual HDFS data blocks. TaskTracker - Responsible for instantiating and monitoring individual Map and Reduce tasks. What is configuration of a typical slave node on Hadoop cluster? How many JVMs run on a slave node? Single instance of a Task Tracker is run on each Slave node. Task tracker is run as a separate JVM process. Single instance of a DataNode daemon is run on each Slave node. DataNode daemon is run as a separate JVM process. One or Multiple instances of Task Instance is run on each slave node. Each task instance is run as a separate JVM process. The number of Task instances can be controlled by configuration. Typically a high end machine is configured to run more task instances. What is the difference between HDFS and NAS ? The Hadoop Distributed File System (HDFS) is a distributed file system designed to run on commodity hardware. It has many similarities with existing distributed file systems. However, the differences from other distributed file systems are significant. Following are differences between HDFS and NAS In HDFS Data Blocks are distributed across local drives of all machines in a cluster. Whereas in NAS data is stored on dedicated hardware. HDFS is designed to work with MapReduce System, since computation are moved to data. NAS is not suitable for MapReduce since data is stored seperately from the computations. HDFS runs on a cluster of machines and provides redundancy usinga replication protocal. Whereas NAS is provided by a single machine therefore does not provide data redundancy. How NameNode Handles data node failures? NameNode periodically receives a Heartbeat and a Blockreport from each of the DataNodes in the cluster. Receipt of a Heartbeat implies that the DataNode is functioning properly. A Blockreport contains a list of all blocks on a DataNode. When NameNode notices that it has not recieved a hearbeat message from a data node after a certain amount of time, the data node is marked as dead. Since blocks will be under replicated the system begins replicating the blocks that were stored on the dead datanode. The NameNode Orchestrates the replication of data blocks from one datanode to another. The replication data transfer happens directly between datanodes and the data never passes through the namenode. Does MapReduce programming model provide a way for reducers to communicate with each other? In a MapReduce job can a reducer communicate with another reducer? Nope, MapReduce programming model does not allow reducers to communicate with each other. Reducers run in isolation. Can I set the number of reducers to zero? Yes, Setting the number of reducers to zero is a valid configuration in Hadoop. When you set the reducers to zero no reducers will be executed, and the output of each mapper will be stored to a separate file on HDFS.

[This is different from the condition when reducers are set to a number greater than zero and the Mappers output (intermediate data) is written to the Local file system(NOT HDFS) of each mappter slave node.] Where is the Mapper Output (intermediate kay-value data) stored ? The mapper output (intermediate data) is stored on the Local file system (NOT HDFS) of each individual mapper nodes. This is typically a temporary directory location which can be setup in config by the hadoop administrator. The intermediate data is cleaned up after the Hadoop Job completes. What are combiners? When should I use a combiner in my MapReduce Job? Combiners are used to increase the efficiency of a MapReduce program. They are used to aggregate intermediate map output locally on individual mapper outputs. Combiners can help you reduce the amount of data that needs to be transferred across to the reducers. You can use your reducer code as a combiner if the operation performed is commutative and associative. The execution of combiner is not guaranteed, Hadoop may or may not execute a combiner. Also, if required it may execute it more then 1 times. Therefore your MapReduce jobs should not depend on the combiners execution. What is Writable & WritableComparable interface? org.apache.hadoop.io.Writable is a Java interface. Any key or value type in the Hadoop Map-Reduce framework implements this interface. Implementations typically implement a static read(DataInput) method which constructs a new instance, calls readFields(DataInput) and returns the instance. org.apache.hadoop.io.WritableComparable is a Java interface. Any type which is to be used as a key in the Hadoop Map-Reduce framework should implement this interface. WritableComparable objects can be compared to each other using Comparators. What is the Hadoop MapReduce API contract for a key and value Class? The Key must implement the org.apache.hadoop.io.WritableComparable interface. The value must implement the org.apache.hadoop.io.Writable interface. What is a IdentityMapper and IdentityReducer in MapReduce ? org.apache.hadoop.mapred.lib.IdentityMapper Implements the identity function, mapping inputs directly to outputs. If MapReduce programmer do not set the Mapper Class using JobConf.setMapperClass then IdentityMapper.class is used as a default value. org.apache.hadoop.mapred.lib.IdentityReducer Performs no reduction, writing all input values directly to the output. If MapReduce programmer do not set the Reducer Class using JobConf.setReducerClass then IdentityReducer.class is used as a default value. What is the meaning of speculative execution in Hadoop? Why is it important? Speculative execution is a way of coping with individual Machine performance. In large clusters where hundreds or thousands of machines are involved there may be machines which are not performing as fast as others. This may result in delays in a full job due to only one machine not performaing well. To avoid this, speculative execution in hadoop can run multiple copies of same map or reduce task on different slave nodes. The results from first node to finish are used. When is the reducers are started in a MapReduce job? In a MapReduce job reducers do not start executing the reduce method until the all Map jobs have completed. Reducers start copying intermediate key-value pairs from the mappers as soon as they are available. The programmer defined reduce method is called only after all the mappers have finished. If reducers do not start before all mappers finish then why does the progress on MapReduce job shows something like Map(50%) Reduce(10%)? Why reducers progress percentage is displayed when mapper is not finished yet? Reducers start copying intermediate key-value pairs from the mappers as soon as they are available. The progress calculation also takes in account the processing of data transfer which is done by reduce process, therefore the reduce progress starts

showing up as soon as any intermediate key-value pair for a mapper is available to be transferred to reducer. Though the reducer progress is updated still the programmer defined reduce method is called only after all the mappers have finished. What is HDFS ? How it is different from traditional file systems? HDFS, the Hadoop Distributed File System, is responsible for storing huge data on the cluster. This is a distributed file system designed to run on commodity hardware. It has many similarities with existing distributed file systems. However, the differences from other distributed file systems are significant. HDFS is highly fault-tolerant and is designed to be deployed on low-cost hardware. HDFS provides high throughput access to application data and is suitable for applications that have large data sets. HDFS is designed to support very large files. Applications that are compatible with HDFS are those that deal with large data sets. These applications write their data only once but they read it one or more times and require these reads to be satisfied at streaming speeds. HDFS supports write-once-read-many semantics on files. What is HDFS Block size? How is it different from traditional file system block size? In HDFS data is split into blocks and distributed across multiple nodes in the cluster. Each block is typically 64Mb or 128Mb in size. Each block is replicated multiple times. Default is to replicate each block three times. Replicas are stored on different nodes. HDFS utilizes the local file system to store each HDFS block as a separate file. HDFS Block size can not be compared with the traditional file system block size. What is a NameNode? How many instances of NameNode run on a Hadoop Cluster? The NameNode is the centerpiece of an HDFS file system. It keeps the directory tree of all files in the file system, and tracks where across the cluster the file data is kept. It does not store the data of these files itself. There is only One NameNode process run on any hadoop cluster. NameNode runs on its own JVM process. In a typical production cluster its run on a separate machine. The NameNode is a Single Point of Failure for the HDFS Cluster. When the NameNode goes down, the file system goes offline. Client applications talk to the NameNode whenever they wish to locate a file, or when they want to add/copy/move/delete a file. The NameNode responds the successful requests by returning a list of relevant DataNode servers where the data lives. What is a DataNode? How many instances of DataNode run on a Hadoop Cluster? A DataNode stores data in the Hadoop File System HDFS. There is only One DataNode process run on any hadoop slave node. DataNode runs on its own JVM process. On startup, a DataNode connects to the NameNode. DataNode instances can talk to each other, this is mostly during replicating data. How the Client communicates with HDFS? The Client communication to HDFS happens using Hadoop HDFS API. Client applications talk to the NameNode whenever they wish to locate a file, or when they want to add/copy/move/delete a file on HDFS. The NameNode responds the successful requests by returning a list of relevant DataNode servers where the data lives. Client applications can talk directly to a DataNode, once the NameNode has provided the location of the data. How the HDFS Blocks are replicated? HDFS is designed to reliably store very large files across machines in a large cluster. It stores each file as a sequence of blocks; all blocks in a file except the last block are the same size. The blocks of a file are replicated for fault tolerance. The block size and replication factor are configurable per file. An application can specify the number of replicas of a file. The replication factor can be specified at file creation time and can be changed later. Files in HDFS are write-once and have strictly one writer at any time. The NameNode makes all decisions regarding replication of blocks.

HDFS uses rack-aware replica placement policy. In default configuration there are total 3 copies of a datablock on HDFS, 2 copies are stored on datanodes on same rack and 3rd copy on a different rack. Can you think of a questions which is not part of this post? Please don't forget to share it with me in comments section & I will try to include it in the list.

Mr. Manasranjan Murlidhar Rana is a certified Hadoop Administrator and an IT professional with 10 years of experience. During his entire career, he has contributed a lot to Hadoop administration for different organizations, including the famous Union Bank of Switzerland.

Mr. Rana’s Knowledge in Hadoop Architecture and its Components

Mr. Manasranjan Murlidhar Rana has vast knowledge and understanding of various aspects related to Hadoop Architecture and its different components. These are MapReduce, YARN, HDFS, HBase, Pig, Flume, Hive, and Zookeeper. He even has the experience to build and maintain multiple clusters in Hadoop, like the production and development of diverse sizes and configurations.

His contribution is observed in the establishment of rack topology to deal with big Hadoop clusters. In this blog post, we will discuss in detail about the massive contribution of Manasranjan Murlidhar Rana as a Hadoop Administrator to deal with various operations of the Union Bank of Switzerland.

Role of Mr. Rana in Union Bank of Switzerland

Right from the year 2016 to until now, Mr. Manasranjan Murlidhar Rana played the role of a Hadoop Administrator with 10 other members for his client named Union Bank of Switzerland. During about 4 years, he worked a lot to enhance the process of data management for his client UBS.

1. Works for the Set up of Hadoop Cluster

Manasranjan Murlidhar Rana and his entire team were involved in the set up of the Hadoop Cluster in UBS right from the beginning to the end procedure. In this way, the complete team works hard to install, configure, and monitor the complete Hadoop Cluster effectively. Here, the Hadoop cluster refers to a computation cluster designed to store and analyze unstructured data in a well-distributed computational environment.

2. Handles 4 Different Clusters and Uses Ambari Server

Mr. Manasranjan Murlidhar Rana is responsible for handling four different clusters of the software development process. These are DEV, UAT, QA, and Prod. He and his entire team even used the innovative Ambari server extensively to maintain different Hadoop cluster and its components. The Ambari server collects data from a cluster and thereby, controls each host.

3. Cluster Maintenance and Review of Hadoop Log Files

Mr. Manasranjan Murlidhar Rana and his team have done many things to maintain the entire Hadoop cluster, along with commissioning plus decommissioning of data nodes. Moreover, he contributed to monitoring different software development related clusters, troubleshoot and manage the available data backups, while reviewed log files of Hadoop. He also reviewed and managed log files of Hadoop as an important of the Hadoop administration to communicate, troubleshoot, and escalate tons of issues to step ahead in the right direction.

4. Successful Installation of Hadoop Components and its Ecosystem

Hadoop Ecosystem consists of Hadoop daemons. Hadoop Daemons in terms of computation imply a process operating in the background and they are of five types, i.e. DataNode, NameNode, TaskTracker, JobTracker, and Secondary NameNode.

Besides, Hadoop has few other components named Flume, Sqoop and HDFS, all of which have specific functions. Indeed, installation, configuration, and maintenance of each of the Hadoop daemons and Hadoop ecosystem components are not easy.

However, based on the hands-on experience of Mr. Manasranjan Rana, he succeeded to guide his entire team to install Hadoop ecosystems and its components named HBase, Flume, Sqoop, and many more. Especially, he worked to use Sqoop to import and export data in HDFS, while to use Flume for loading any log data directly into HDFS.

5. Monitor the Hadoop Deployment and Other Related Procedures

Based on the vast knowledge and expertise to deal with Hadoop elements, Mr. Manasranjan Murlidhar Rana monitored systems and services, work for the architectural design and proper implementation of Hadoop deployment and make sure of other procedures, like disaster recovery, data backup, and configuration management.

6. Used Cloudera Manager and App Dynamics

Based on the hands-on experience of Mr. Manasranjan Murlidhar Rana to use App Dynamics, he monitored multiple clusters and environments available under Hadoop. He even checked the job performance, workload, and capacity planning with the help of the Cloudera Manager. Along with this, he worked with varieties of system engineering aspects to formulate plans and deploy innovative Hadoop environments. He even expanded the already existing Hadoop cluster successfully.

7. Setting Up of My-SQL Replications and Maintenance of My-SQL Databases

Other than the expertise of Mr. Manasranjan Murlidhar Rana in various aspects of Bigdata, especially the Hadoop ecosystem and its components, he has good command on different types of databases, like Oracle, Ms-Access, and My-SQL.

Thus, according to his work experience, he maintained databases by using My-SQL, established users, and maintained the backup or recovery of available databases. He was also responsible for the establishment of master and slave replications for the My-SQL database and helped business apps to maintain data in various My-SQL servers.

Therefore, with good knowledge of Hadoop Ambari Server, Hadoop components, and demons, along with the entire Hadoop Ecosystem, Mr. Manasranjan Murlidhar Rana has given contributions towards the smart management of available data for the Union Bank of Switzerland.
