Subject [jira] [Commented] (YARN-376) Apps that have completed can appear as RUNNING on the NM UI
Date Thu, 28 Feb 2013 03:27:13 GMT

    [ https://issues.apache.org/jira/browse/YARN-376?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13589136#comment-13589136

Jason Lowe commented on YARN-376:
---------------------------------

The eclipse failure appears to be unrelated, as it builds fine for me locally.  Also I can't
see how this change would affect the eclipse:eclipse build which is failing in hadoop-common.

> 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.
