This is the documentation for Cloudera Enterprise 5.12.x. Documentation for other versions is available at Cloudera Documentation.

Before You Install CDH 5 on a Single Node

  Important:
  • Follow these command-line instructions on systems that do not use Cloudera Manager.
  • This information applies specifically to CDH 5.12.x. See Cloudera Documentation for information specific to other releases.
  Note: When starting, stopping and restarting CDH components, always use the service (8) command rather than running /etc/init.d scripts directly. This is important because service sets the current working directory to / and removes most environment variables (passing only LANG and TERM) so as to create a predictable environment in which to administer the service. If you run the /etc/init.d scripts directly, any environment variables you have set remain in force, and could produce unpredictable results. (If you install CDH from packages, service will be installed as part of the Linux Standard Base (LSB).)

Before you install CDH 5 on a single node, there are some important steps you need to do to prepare your system:

  1. Verify you are using a supported operating system for CDH 5. See CDH and Cloudera Manager Supported Operating Systems.
  2. If you haven't already done so, install the JDK before deploying CDH 5.
