> FairScheduler: FSLeafQueue.fetchAppsWithDemand CPU usage is high with big
> queues
> --------------------------------------------------------------------------------
>
> Key: YARN-6361
> URL: https://issues.apache.org/jira/browse/YARN-6361
> Project: Hadoop YARN
> Issue Type: Sub-task
> Reporter: Miklos Szegedi
> Assignee: YunFan Zhou
> Attachments: dispatcherthread.png, threads.png, YARN-6361.001.patch
>
>
> FSLeafQueue.fetchAppsWithDemand sorts the applications by the current policy.
> Most of the time is spent in FairShareComparator.compare. We could improve
> this by doing the calculations outside the sort loop {{(O\(n\))}} and we
> sorted by a fixed number inside instead {{O(n*log\(n\))}}. This could be an
> performance issue when there are huge number of applications in a single
> queue. The attachments shows the performance impact when there are 10k
> applications in one queue.
