Subru Krishnan commented on YARN-2738:

Thanks [~adhoot] and [~kasha] for taking the time for offline discussions. The 
consensus is that for the first iteration we will have a single boolean flag 
per leaf queue to specify whether the queue is reservable or not. This is 
mutually exclusive to the _parent_ flag, i.e. either a leaf queue can be a 
dynamic parent queue or it can be reservable. We will have defaults for 
_ReservationAgent_, _Replanner_ etc which will be overrideable at scheduler 

I agree with [~kasha] that we should hide the dynamic reservation queues from 
the user. Can we use 
_ReservationSchedulerConfiguration::getShowReservationAsQueues_ to show/hide 
the dynamic reservation queues in web UI?

Also we need the equivalent of _CapacityScheduler::resolveReservationQueueName_ 
for the _AppAddedSchedulerEvent_ in FS and _handleMoveToPlanQueue_ for
