Subject [jira] [Created] (YARN-965) NodeManager Metrics containersRunning is not correct When localizing container process is failed or killed
Date Wed, 24 Jul 2013 06:43:48 GMT
Li Yuan created YARN-965:
----------------------------

             Summary: NodeManager Metrics containersRunning is not correct When localizing
container process is failed or killed
                 Key: YARN-965
                 URL: https://issues.apache.org/jira/browse/YARN-965
             Project: Hadoop YARN
          Issue Type: Bug
          Components: nodemanager
    Affects Versions: 2.0.4-alpha
         Environment: suse linux
            Reporter: Li Yuan
             Fix For: 2.1.0-beta


When successfully launched a container, container state from LOCALIZED to RUNNING, containersRunning
++. Container state from EXITED_WITH_FAILURE or KILLING to DONE, containersRunning--. 
However, state EXITED_WITH_FAILURE or KILLING could come from LOCALIZING(LOCALIZED), not RUNNING,
which caused containersRunningis less than the actual number. Further more, Metrics is wrong,
containersLaunched != containersCompleted + containersFailed + containersKilled + containersRunning
+ containersIniting
