Description

Currently Oozie requires the JT and NN kerberos principals to be in the WF job properties when submitting a job.

Hadoop has built in rules to create these principals (i.e. mapred/_HOST@${local.realm}).

Oozie should leverage those rules if the WF job properties do not include JT/NN kerberos principals thus not requiring them as mandatory WF job properties on WF submission.
