> FairScheduler performance bug
> -----------------------------
>
> Key: YARN-5188
> URL: https://issues.apache.org/jira/browse/YARN-5188
> Project: Hadoop YARN
> Issue Type: Bug
> Components: fairscheduler
> Affects Versions: 2.5.0, 2.8.0
> Reporter: ChenFolin
> Attachments: YARN-5188.patch
>
>
> My Hadoop Cluster has recently encountered a performance problem. Details as
> Follows.
>
> The efficiency of assign container in the Resourcemanager may fall
> when the number of running and pending application grows. And the fact is the
> cluster has too many PendingMB or PengdingVcore , and the Cluster
> current utilization rate may below 20%.
> I checked the resourcemanager logs, I found that every assign
> container may cost 5 ~ 10 ms, but just 0 ~ 1 ms at usual time.
>
> I use TestFairScheduler to reproduce the scene:
>
> Just one queue: root.defalut
> 10240 apps.
>
> assign container avg time: 6753.9 us ( 6.7539 ms)
> apps sort time (FSLeafQueue : Collections.sort(runnableApps,
> comparator); ): 4657.01 us ( 4.657 ms )
> compute LeafQueue Resource usage : 905.171 us ( 0.905171 ms )
>
> When just root.default, one assign container op contains : ( one apps
> sort op ) + 2 * ( compute leafqueue usage op )
> According to the above situation, I think the assign container op has
> a performance problem .
