> URL: https://issues.apache.org/jira/browse/YUNIKORN-3133
> Project: Apache YuniKorn
> Issue Type: New Feature
> Components: core - scheduler, release-notes
> Reporter: Manikandan R
> Assignee: Manikandan R
> Priority: Major
> Fix For: 1.8.0

>
> When a quota is lowered we currently just stop scheduling workloads in that
> queue or set of queues. We then rely on the natural pod exits to lower the
> usage below the new quota set and then continue scheduling.
> This work with short lived applications. It does not work if the workload is
> long lived.
> Need to look at implementing preemption to lower the usage to the queue quota
> within some guidelines
> * preempt most recent container?
> * grace period allowed?
> * daemon set exclusion
