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?
Thanks,
Wangda
