Subject [jira] Commented: (MAPREDUCE-430) Task stuck in cleanup with OutOfMemoryErrors
Date Tue, 21 Jul 2009 15:15:14 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-430?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12733656#action_12733656

Arun C Murthy commented on MAPREDUCE-430:
-----------------------------------------

bq. No. The task alive and stuck. I think pingThread was sending updates without any problem.

That worries me. Do we know why the jvm did not shutdown? Where did we catch and ignore the
OOMError? Is the ping thread not a daemon-thread?
