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 CDH, Cloudera's 100% open source platform containing Apache Hadoop and related projects (CDH 5), and how to deploy it on a cluster.

The guide covers the following major topics.

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.

  Note: Use these instructions to migrate data from a CDH 4 cluster to a CDH 5 cluster.
