Zookeeper Installation

Download the stable version of HBase. In our case it is HBase 0.94.16.

• Execute following command to download HBase 0.94.16

  wget  http://apache.mirror.quintex.com/zookeeper/stable/zookeeper-3.4.5.tar.gz

  
• Unzip the compressed hbase file by executing the following command:

  tar -xvzf zookeeper-3.4.5.tar.

  
• Login as root and create a directory “zookeeper”, Change the ownership of this directory to the hadoop user “hduser” and group “hadoop”. This is done mainly for our convenience, to differentiate each framework, software and application with different users. Execute the following commands

  cd /usr/local
  mkdir zookeeper
  chown -R hduser:hadoop /usr/local/zookeeper

  
• Copy the unzipped zookeeper binaries into /usr/local/zookeeper folder

  mv zookeeper-3.4.5 /usr/local/

  
• To start zookeeper, you need a configuration file. Create a configuration file named, zoo.cfg file in the path /usr/local/zookeeper/conf. Eexcute the following commands

  cd /usr/local/zookeeper/zookeeper-3.4.5/conf
  vi zoo.cfg

  
• Add the following entries to the file.

  tickTime=2000
  dataDir=/usr/local/zookeeper/data
  clientPort=2181

  
• Start Zookeeper by executing the following command.

  ./zkServer.sh start
  JMX enabled by default
  Using config: /usr/local/zookeeper/zookeeper-3.4.5/bin/../conf/zoo.cfg
  Starting zookeeper ... STARTED

  
• Zookeeper is now set up and is ready for further use. Zookeeper logs messages using.
• The steps outlined here run Zookeeper in standalone mode. There is no replication, so if Zookeeper process fails, the service will go down.
• Stop Zookeeper by executing the following command.

  ./zkServer.sh stop
  JMX enabled by default
  Using config: /usr/local/zookeeper/zookeeper-3.4.5/bin/../conf/zoo.cfg
  Stopping zookeeper ... ./zkServer.sh: line 143: kill: (6411) - No such process
