CDH 5 Installation Guide

This CDH 5 Installation Guide is for Apache Hadoop developers and system administrators interested in Hadoop installation. It describes how to install and configure version 5 of Cloudera's Distribution Including Apache Hadoop (CDH 5), and how to deploy it on a cluster.

The guide covers the following major topics.

Before You Start:
Installation tasks:
  • Install CDH 5. Start here for a new installation on a cluster.
  • Deploy CDH 5. Do these tasks after installing core Hadoop.
  • Install components. Install additional components after installing and deploying HDFS and MapReduce. (Components are listed below.)
  Note:

To install a release earlier than the current CDH 5 release (for example if you want to add new nodes to a cluster without upgrading the cluster to the latest release), follow these instructions.

Upgrade tasks:
  • Upgrade from CDH 4 to CDH 5. Use these instructions if you are currently running a CDH 4 release; or
  • Upgrade from an earlier CDH 5 release. Use these instructions if you are currently running a CDH 5 release.
  • Upgrade components. Upgrade all installed components after upgrading core Hadoop. (Components are listed below.)
  Note: Use these instructions to migrate data from a CDH 4 cluster to a CDH 5 cluster.
