By default when you do not specify this option, Ambari Server setup downloads the Oracle JDK 1.8 binary and accompanying Java Cryptography Extension (JCE) Policy Files to /var/lib/ambari-server/resources. Ambari Server then installs the JDK to /usr/jdk64.

Use this option when you plan to use a JDK other than the default Oracle JDK 1.8. If you are using an alternate JDK, you must manually install the JDK on all hosts and specify the Java Home path during Ambari Server setup. If you plan to use Kerberos, you must also install the JCE on all hosts.

This path must be valid on all hosts. For example:

ambari-server setup –j /usr/java/default
