> This only applies to fair scheduler. Capacity scheduler is OK.
> When appAttempt or node is removed, the metrics for 
> reservation(reservedContainers, reservedMB, reservedVCores) is not reduced 
> back.
> These are important metrics for administrator. The wrong metrics confuses may 
> confuse them.
