Subject [jira] Commented: (MAPREDUCE-1102) Job gets killed even when the cleanup completes
Date Mon, 26 Oct 2009 16:00:59 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1102?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12770071#action_12770071

Owen O'Malley commented on MAPREDUCE-1102:

Rather than blocking kill-job, I think we are better off guaranteeing that if the job fails,
we will always call abortJob. Even if commitJob has started (or finished). We should also
make the FileOutputFormat abortJob delete _SUCCESS to handle this case. This would also handle
the case where the job commit task fails part way through.

I agree that all output committers may not be able to unroll their commit. However, I think
that we need to give them the ability to do the right thing.

> When the cleanup completes at the tasktracker and the job is killed by the user, the
cleanup runs to completion but the job fails. Ideally if the cleanup is completed then the
job should not be killed.
