> Key: YARN-2285
> URL: https://issues.apache.org/jira/browse/YARN-2285
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: capacityscheduler
> Affects Versions: 2.5.0
> Environment: Turn on CS Preemption.
> Reporter: Tassapol Athiapinya
> Assignee: Wangda Tan
> Priority: Minor

> I configure queue A, B to have 1%, 99% capacity respectively. There is no max capacity for each queue. Set high user limit factor.
> Submit app 1 to queue A. AM container takes 50% of cluster memory. Task containers take another 50%. Submit app 2 to queue B. Preempt task containers of app 1 out. Turns out capacity of queue B increases to 99% but queue A has 5000% used.
