Wangda Tan commented on YARN-4945:
----------------------------------
[~eepayne], I totally agree that intra-queue preemption should happen only if
applications belong to the queue cannot get resource outside of the queue.
These bounds are: resources / partitions / user-limits. However, I think for
non-accountable (like First-come-first-serve) usage, for example locality,
should not trigger preemption. Preemption of FCFS usages could lead to
excessive-preemption.
And [~sunilg] is also working on a POC / design, I think you can collaborate on
this. Sunil, could you give some brief updates of the POC/design efforts?
