Yufei Gu commented on YARN-7057:
--------------------------------
Looking around the code, {{getPendingDemand()}} shouldn't be affected in a bad
way, it will actually be affect in a good way. One of callers of
{{getPendingDemand()}} decides which application is starve. Without this
change, {{updateStarvedApps}} looks fishy.
> FSAppAttempt#getResourceUsage doesn't need to consider resources queued for
> preemption
