Haibo Chen commented on YARN-6672:
----------------------------------
Attached a patch to do the NM periodical preemption. In the meantime, I notice
that there is a disabled unit test in TestContainerSchedulerWithOverAllocation
that was supposed to be removed in YARN-8427, so I did that too in this patch.
> Add NM preemption of opportunistic containers when utilization goes high
