1. Install CDH packages on the appropriate hosts, as follows:
   • RHEL Compatible:

     sudo yum install <package_name> [<package_name>...]

   • SLES:

     sudo zypper install <package_name> [<package_name>...]

   • Ubuntu:

     sudo apt-get install <package_name> [<package_name>...]

   The following table lists the package names for each component.

     Note: Most of the packages below contain only init.d scripts for the associated services, but have dependencies on the core software. Your package manager will automatically install the required dependent packages. For example, installing zookeeper-server will also automatically install zookeeper.

This section explains how to install LZO ( Lempel–Ziv–Oberhumer) compression. For more information, see Choosing and Configuring Data Compression.

1. Add the repository on each host in the cluster. Follow the instructions for your OS version:
   • RHEL Compatible:

     sudo wget -O /etc/yum.repos.d/ https://archive.cloudera.com/gplextras5/redhat/<version>/x86_64/gplextras/cloudera-gplextras5.repo

     Replace <version> with your RHEL version: 7, 6, or 5

   • SLES 12:

     sudo zypper addrepo -f https://archive.cloudera.com/gplextras5/sles/<version>/x86_64/gplextras/cloudera-gplextras5.repo

     Replace <version> with your SLES version: 12 or 11

   • Ubuntu:

     sudo wget -O /etc/apt/sources.list.d/ https://archive.cloudera.com/gplextras5/ubuntu/<version>/amd64/gplextras/cloudera-gplextras.list

     Replace <version> with your Ubuntu version: xenial, trusty, precise, or lucid

   • Debian:

     sudo wget -O /etc/apt/sources.list.d/ https://archive.cloudera.com/gplextras5/debian/<version>/amd64/gplextras/cloudera.list

     Replace <version> with your Debian version: jessie, squeeze, or wheezy

2. Install the hadoop-lzo package:
   • RHEL compatible:

     sudo yum install hadoop-lzo

   • SLES:

     sudo zypper install hadoop-lzo

   • Ubuntu, Debian:

     sudo apt-get install hadoop-lzo

3. Continue with installing and deploying CDH. As part of the deployment, you will need to do some additional configuration for LZO, as shown under Configuring LZO.
     Important: Be sure to do this configuration after you have copied the default configuration files to a custom location and set alternatives to point to it.

Proceed to Step 5: Set Up a CDH Cluster.
