Hadoop Start Commands

Hadoop Commands

Hadoop Process Start/Stop:

  • start-all.sh   => starting NameNode, DataNode, Secondary NameNode, Resource Manager, Node Manager

  • stop-all.sh    => stopping NameNode, DataNode, Secondary NameNode, Resource Manager, Node Manager
  • start-dfs.sh  =>  starting NameNode, DataNode, Secondary NameNode
  • stop-dfs.sh   => stopping NameNode, DataNode, Secondary NameNode

Hadoop 1.x:
  • start-mapred.sh => starting Job Tracker, Task Tracker
  • stop-mapred.sh => stopping Job Tracker, Task Tracker

Hadoop 2.x:
  • start-yarn.sh  => starting Resource Manager, Node Manager
  • stop-yarn.sh   => stopping Resource Manager, Node Manager

For starting individual service:

For hdfs services

hadoop-daemon.sh start <process_name>
hadoop-daemon.sh stop <process_name>

Ex: process_names are `namenode, datanode, secondarynamenode`
Ex: For NameNode process
  • hadoop-daemon.sh start namenode
  • hadoop-daemon.sh stop namenode
-------------------------------------------------------------------------------------

For yarn services

yarn-daemon.sh start <process_name>
yarn-daemon.sh stop <process_name>

Example: process_names are `resourcemanager, nodemanager`
Example: For resourcemanager process
  • yarn-daemon.sh start resourcemanager
  • yarn-daemon.sh stop resourcemanager

What is Hadoop ? Hadoop is a framework that allows us to store and process large data sets in parallel and distributed fashion. It was developed by Doug Cutting in 2005, was working in yahoo. It efficiently store and process large datasets ranging in size 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 massive datasets in parallel more quickly. Hadoop is used for Batch processing where, f irst data is collected, entered and then processed. Later, it produces batch result. It uses master-slave architecture where one master and multiple slave works in a cluster.. Hadoop uses commodity hardware. So, it is cost effective. It is scalable as per requirement. Hadoop deals with flat files in any format. Hadoop follows RPC communication model. By default, Communication happens in every 3 seconds where slave communicates to master. There are three components of Hadoop: HDFS  - Hado...

Rack Awareness Algorithm

Block -   Block is a small chunk of data. It contains minimum amount of data that can be read or write. HDFS stores each file in terms of blocks. Block size in Hadoop 1x is 64 MB. Block size in Hadoop 2x is 128 MB. Files are split into 64 MB or 128 MB blocks depending on Hadoop version and then stored into the Hadoop file system. Why HDFS block size are large in size Reason for having HDFS blocks in large size is to reduce the cost of seek time. In general, the seek time is 10 ms and disk transfer rate is 100 MB/S. To make the seek time 1% of the disk transfer rate, the block size should be 100 MB. The default size HDFS block is 64 MB. Rack  - Rack is a collection of machine which are connected using same network switch. If the network goes down, all the machine in a network will go down. Rack Awareness algorithm came into the picture to overcome this problem. In Rack Awareness, NameNode chooses the DataNode which is closer to the same rack or nearby rack. NameNode maintains...

Big Data

What is Big Data ? Big Data refers to large amount of data sets that can not be efficiently managed by the common database management system. Extremely large data sets that may be analyzed computationally to reveal patterns, trends, and associations, especially relating to human behavior and interaction. Data increasing day by day 1 ZB = 1000 EB 1 EB = 1000 PB 1 PB = 1000 TB 1 TB = 1000 GB 1 GB = 1000 MB 1 MB = 1000 KB 1 KB = 1000 BYTE Note - Around 2.5 quintillion bytes of data is generated every day in all over the world, calculated by IBM.
