CDH4 Installation Guide

This CDH4 Installation Guide is for Apache Hadoop developers and system administrators interested in Hadoop installation. It describes how to install and configure version 4 of Cloudera's Distribution Including Apache Hadoop (CDH4), and how to deploy it on a cluster.

The guide covers the following major topics.

Installation tasks:
  • Install CDH4. Start here for a new installation on a cluster.
  • Deploy CDH4. Do these tasks after installing core Hadoop.
  • Install components. Install additional components after installing and deploying HDFS and MapReduce.
  Note: To install a release earlier than the current CDH4 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:
  Note: Use these instructions to migrate data from a CDH3 cluster to a CDH4 cluster.
