> On newly added nn5 and nn6 I see the Start NN call waits for JMX to return,
> we are not starting Ranger so NN JMX does not respond. However there seems to
> be logic to skip the check if Ranger Admin is not up:
> {code}
> 2018-04-20 18:34:29,072 - RangeradminV2: Skip ranger admin if it's down !
> 2018-04-20 18:34:29,093 - checked_call['/usr/bin/kinit -c

> {'user': 'hdfs'}
> 2018-04-20 18:34:29,183 - checked_call returned (0, '')
> {code}
> Still we are waiting for a long time and them actually succeeding.
> If Ranger being up is needed please assign this appropriately to UI team to
> make sure we start required services before Starting NN. If the skip check is
> desired behavior we should be able to proceed in that case.
