i followed the instructions here: <http://docs.hortonworks.com/HDPDocuments/Am
bari-2.2.1.0/bk_ambari_reference_guide/content/ch_changing_the_jdk_version_on_
an_existing_cluster.html>

one issue was the above doc did not say i need to restart ambari server for
the new java home to be picked up when i restart.

I went from JDK 7 and to JDK 8 and restarted oozie server and it failed with
error like:

Issue is that

[root@hcube1-1n03 ~]# ls /var/lib/ambari-agent/tmp/jdk
jdk1.7.0_67 jdk1.8.0_60

already has jdk 1.7 unpcaked.

We should change the cp command to only copy the specific directory

ambari-sudo.sh cp -rp /var/lib/ambari-agent/tmp/jdk/*

We are also missing the JCE setup from the upgraded JDK.
