Junping Du commented on YARN-670:
---------------------------------

Resolve this as won't fix as Rolling upgrade won't need Maintenance model as 
containers can still be running when NM goes down. For gracefully decommission, 
we have YARN-3212 to make sure no new container get assigned on decommissioning 
container.

> Add an Exception to indicate 'Maintenance' for NMs and add this to the 
> JavaDoc for appropriate protocols
