> Key: YARN-5540
> URL: https://issues.apache.org/jira/browse/YARN-5540
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: capacity scheduler, fairscheduler, resourcemanager
> Affects Versions: 2.7.2
> Reporter: Nathan Roberts
> Assignee: Jason Lowe
> Attachments: YARN-5540-branch-2.7.004.patch,
> YARN-5540-branch-2.8.004.patch, YARN-5540.001.patch, YARN-5540.002.patch,

>
> We're starting to see the capacity scheduler run out of scheduling horsepower
> when running 500-1000 applications on clusters with 4K nodes or so.
> This seems to be amplified by TEZ applications. TEZ applications have many
> more priorities (sometimes in the hundreds) than typical MR applications and
> therefore the loop in the scheduler which examines every priority within
> every running application, starts to be a hotspot. The priorities appear to
> stay around forever, even when there is no remaining resource request at that
> priority causing us to spend a lot of time looking at nothing.
