Installing Oracle JDK for CDP Runtime

This section is optional. The CDP Runtime requires a JDK to be installed on all cluster hosts prior to Cloudera Manager and Runtime installation. Cloudera Manager can automatically install an OpenJDK that has been pre-packaged by Cloudera. This OpenJDK provided by Cloudera may not be the latest version. If you do not want to use the OpenJDK provided by Cloudera, you can follow these instructions to install the Oracle JDK.

The Oracle JDK must be installed on all cluster hosts. The Oracle JDK installer is available both as an RPM-based installer for RPM-based systems, and as a .tar.gz file. These instructions are for the .tar.gz file.

Download the .tar.gz file for one of the 64-bit supported versions of the Oracle JDK from Java SE 8 Downloads.

note
If you want to download the JDK directly using a utility such as wget, you must accept the Oracle license by configuring headers, which are updated frequently. Blog posts and Q&A sites can be a good source of information on how to download a particular JDK version using wget.

Extract the JDK to /usr/java/jdk-version. For example:

tar xvfz /path/to/jdk-8u<update_version>-linux-x64.tar.gz -C /usr/java/

Repeat this procedure on all cluster hosts.

After you have finished, continue to Step 3: Install Cloudera Manager Server.
