Tao Yang commented on YARN-9007:
--------------------------------
Add "for queue and reserved container preemption" to the end of this issue
name. This issue is proposed to skip selecting OPPORTUNISTIC containers for the
policies which want to balance GUARANTEED resource in preemption monitor.
> CS preemption monitor should only select GUARANTEED containers as candidates
> for queue and reserved container preemption

> Project: Hadoop YARN
> Issue Type: Bug
> Components: capacityscheduler
> Affects Versions: 3.2.1
> Reporter: Tao Yang
> Assignee: Tao Yang
> Priority: Major
> Attachments: YARN-9007.001.patch

>
> Currently CS preemption monitor doesn't consider execution type of
> containers, so OPPORTUNISTIC containers maybe selected and killed without
> effect.
> In some scenario with OPPORTUNISTIC containers, not even preemption can't
> work properly to balance resources, but also some apps with OPPORTUNISTIC
> containers maybe effected and unable to work.
