Manually Installing Oracle JDK

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.
