-------------------------------

             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.
