> Project: Hadoop YARN
> Issue Type: Bug
> Components: capacityscheduler
> Affects Versions: 2.6.0
> Reporter: Thomas Graves
> Assignee: Thomas Graves

> ULF was set to 1.0
> User was able to consume 1.4X queue capacity.
> It looks like when this application launched, it reserved about 1000
> containers, each 8G each, within about 5 seconds. I think this allowed the
> logic in assignToUser() to allow the userlimit to be surpassed.
