Wangda Tan commented on YARN-2056:

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.

Does it make sense?
