[jira] [Created] (YARN-2306) leak of reservation metrics

Hong Zhiguo created YARN-2306:
---------------------------------

             Summary: leak of reservation metrics
                 Key: YARN-2306
                 URL: https://issues.apache.org/jira/browse/YARN-2306
             Project: Hadoop YARN
          Issue Type: Bug
          Components: scheduler
            Reporter: Hong Zhiguo
            Assignee: Hong Zhiguo
            Priority: Minor


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.
