In addition each "leaked" application in the NM has a corresponding log aggregation thread in the NM and eventually it will be unable to create new threads. > 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 > Assignee: Jason Lowe > Priority: Blocker > Attachments: YARN-376.patch > > > 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. -- This message is automatically generated by JIRA.
