Eric Payne commented on YARN-2056:

Thanks, [~leftnoteasy]
May a another way to do this is add a config in per queue, like 
..queue-path.disable_preemption. And in 
ProportionalCapacityPreemptionPolicy#cloneQueues, if a queue's used capacity 
more than guaranteed resource, and it set disable preemption. We will not 
create a TempQueue for it.
 We will not require RM restart if queue property changed (queue property will 
be refreshed and PreemptionPolicy will get such changes.

I am fine with this. [~mayank_bansal] (originator) and others, can you please
