[jira] [Commented] (MAPREDUCE-3333) MR AM for sort-job going out of
memory
[ https://issues.apache.org/jira/browse/MAPREDUCE-3333?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13142162#comment-13142162 ]
Vinod Kumar Vavilapalli commented on MAPREDUCE-3333:
----------------------------------------------------
It wasn't so hard to track this down, given one of my earlier patches causes this - MAPREDUCE-3256.
My mistake. AM now tries to create one thread per container instead of the earlier and the correct behaviour of one thread per node.

> [~Karams] just found this. The usual sort job on a 350 node cluster hung due to OutOfMemory and eventually failed after an hour instead of the usual odd 20 minutes.
