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

Integrated in Hadoop-Mapreduce-trunk #1359 (See [https://builds.apache.org/job/Hadoop-Mapreduce-trunk/1359/])

applications. Contributed by Jason Lowe. (Revision 1451473)

     Result = SUCCESS

> 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.
