Daniel Templeton commented on YARN-7057:
----------------------------------------
OK, I double-check the uses of {{getResourceUsage()}}, and I agree. The change
ranges from benign to necessary, depending on the caller. The only one that's
a little suspicious is {{isStarvedForFairShare()}}, where it seems we might now
be penalizing the app for the to-be-preempted resources. [~yufeigu], if you're
happy with it, I think it's OK to commit.
> FSAppAttempt#getResourceUsage doesn't need to consider resources queued for
