Subject [jira] [Commented] (MAPREDUCE-3888) Ensure/confirm that the NodeManager cleanup their local filesystem when they restart
Date Wed, 22 Feb 2012 02:06:48 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3888?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13213189#comment-13213189
] 

Hitesh Shah commented on MAPREDUCE-3888:
----------------------------------------

Actually, given that now we have the container.pid files, we should be to kill containers
from the earlier NM instance too. Will file a separate jira to kill running containers both
on an NM shutdown as well on startup ( for unclean shutdowns ).

> It may already be working like that in which case we should have tests validating this.
