Subject [jira] [Commented] (YARN-2261) YARN should have a way to run post-application cleanup
Date Sat, 01 Nov 2014 18:19:34 GMT

    [ https://issues.apache.org/jira/browse/YARN-2261?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14193324#comment-14193324
] 

Steve Loughran commented on YARN-2261:
--------------------------------------

One problem with this proposal as is that it doesn't address AM failure, especially for the
final "will not be restarted" operation. 

If an AM could specify the cleanup routine to execute on cleanup (same resources as for the
normal AM), this would be possible. For Slider we'd just add a new CLI option to the same
entry point, something like {{-D slider.am.cleanup=true}}
