Subject [jira] [Created] (YARN-376) Apps that have completed can appear as RUNNING on the NM UI
Date Mon, 04 Feb 2013 19:34:13 GMT
Jason Lowe created YARN-376:

             Summary: Apps that have completed can appear as RUNNING on the NM UI
                 Key: YARN-376
                 URL: https://issues.apache.org/jira/browse/YARN-376
             Project: Hadoop YARN
          Issue Type: Bug
          Components: resourcemanager
    Affects Versions: 2.0.3-alpha, 0.23.6
            Reporter: Jason Lowe

On a busy cluster we've noticed a growing number of applications appear as RUNNING on a nodemanager
web pages but the applications have long since finished.  Looking at the NM logs, it appears
the RM never told the nodemanager that the application had finished.  This is also reflected
in a jstack of the NM process, since many more log aggregation threads are running then one
would expect from the number of actively running applications.
