Zookeeper Installation Guide

- 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.
