Before You Install CDH 5 on a Single Node
Important:
- If you use Cloudera Manager, do not use these command-line instructions.
- This information applies specifically to CDH 5.8.x. If you use a lower version of CDH, see the documentation for that version located at Cloudera Documentation.
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:
- Verify you are using a supported operating system for CDH 5. See CDH 5 Requirements and Supported Versions.
- If you haven't already done so, install the JDK before deploying CDH 5.
