> This test should only work for capacity scheduler because the following source code in ResourceManager.java prove it will only work for capacity scheduler.

> if (scheduler instanceof PreemptableResourceScheduler

> Because CapacityScheduler is instance of PreemptableResourceScheduler and FairScheduler is not instance of PreemptableResourceScheduler.
> I will upload a patch to fix this issue.
