Jian Fang commented on YARN-2306:
---------------------------------

Could someone please tell me which JIRA has fixed this bug in trunk? I am working on hadoop
2.6.0 branch and need to see if I need to fix this issue or not. Thanks in advance.

> 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.
