Failed job leaves hung AM after it unregisters (Jason Lowe via jeagles) (jeagles: http://svn.apache.org/viewcvs.cgi/?root=Apache-SVN&view=rev&rev=1594317) * /hadoop/common/trunk/hadoop-mapreduce-project/CHANGES.txt * /hadoop/common/trunk/hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client-app/src/main/java/org/apache/hadoop/mapreduce/v2/app/job/impl/JobImpl.java > Failed job leaves hung AM after it unregisters > ----------------------------------------------- > > Key: MAPREDUCE-5888 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-5888 > Project: Hadoop Map/Reduce > Issue Type: Bug > Components: mr-am > Affects Versions: 2.2.0 > Reporter: Jason Lowe > Assignee: Jason Lowe > Fix For: 3.0.0, 2.5.0 > > Attachments: MAPREDUCE-5888.patch > > > When a job fails the AM hangs during shutdown. A non-daemon thread pool > executor thread prevents the JVM teardown from completing, and the AM lingers > on the cluster for the AM expiry interval in the FINISHING state until > eventually the RM expires it and kills the container. If application limits > on the queue are relatively low (e.g.: small queue or small cluster) this can > cause unnecessary delays in resource scheduling on the cluster. -- This message was sent by Atlassian JIRA (v6.2#6252)
