> Negative vcore for resource needed to preempt
> ---------------------------------------------
>
> Key: YARN-6175
> URL: https://issues.apache.org/jira/browse/YARN-6175
> Project: Hadoop YARN
> Issue Type: Bug
> Components: fairscheduler
> Affects Versions: 2.8.0
> Reporter: Yufei Gu
> Assignee: Yufei Gu
> Attachments: YARN-6175.001.patch
>
>
> Both old preemption code (2.8 and before) and new preemption code could have
> negative vcores while calculating resources needed to preempt.
> For old preemption, you can find following messages in RM logs:
> {code}
> Should preempt <memory:2048, vCores:-2>
> {code}
> The related code is in method {{resourceDeficit()}}.
> For new preemption code, there are no messages in RM logs, the related code
> is in method {{fairShareStarvation()}}.
> The negative value isn't only a display issue, but also may cause missing
> necessary preemption.
