> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: mrv2
> Affects Versions: 0.23.0
> Reporter: Ramya Sunil

>
> AvailableGB per queue is not the same as AvailableGB per queue per user when
> the user limit is set to 100%.
> i.e. if the total available GB of the cluster is 60, and queue "default" has
> 92% capacity with 100% as the user limit, AvailableGB per queue default = 55
> (i.e. 0.92*60) whereas AvailableGB per queue for user ramya is 56 (however it
> should be 55 = 0.92*60*1)
> Also, unlike the AvailableGB/queue, AvailableGB/queue/user is not decremented
> when user ramya is running apps on the "default" queue.
