> 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.
