This is the documentation for CDH 5.0.x. Documentation for other versions is available at Cloudera Documentation.

Starting CDH Services

You need to start and stop services in the right order to make sure everything starts or stops cleanly.

Note: The Oracle JDK is required for all Hadoop components.

START services in this order:

Order	Service	Comments	For instructions and more information
