[jira] [Created] (YARN-2825) Container leak on NM

Jian He created YARN-2825:
-----------------------------

             Summary: Container leak on NM
                 Key: YARN-2825
                 URL: https://issues.apache.org/jira/browse/YARN-2825
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Jian He
            Assignee: Jian He
            Priority: Critical


Caused by YARN-1372. thanks [~vinodkv] for pointing  this out.

The problem is that in YARN-1372 we changed the behavior to remove containers from NMContext only after the containers are acknowledged  by AM. But in the {{NodeStatusUpdaterImpl#removeCompletedContainersFromContext}} call, we didn't check whether the container is really completed or not.  If the container is stilll running, we shouldn't remove the container from the context
