Before You Install CDH 5 on a Single Node

  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 5 Requirements and Supported Versions.
  2. If you haven't already done so, install the Oracle Java Development Kit (JDK) before deploying CDH 5.
