> Affects Versions: 2.6.0, 2.7.0, 2.8.0
> Reporter: Eric Payne
> Assignee: Eric Payne
> Attachments: YARN-3769-branch-2.002.patch,

>
>
> We are seeing the preemption monitor preempting containers from queue A and
> then seeing the capacity scheduler giving them immediately back to queue A.
> This happens quite often and causes a lot of churn.
