Subject [jira] [Commented] (MAPREDUCE-4092) commitJob Exception does not fail job (regression in 0.23 vs 0.20)
Date Mon, 02 Apr 2012 15:39:26 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-4092?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13244263#comment-13244263
] 

Robert Joseph Evans commented on MAPREDUCE-4092:
------------------------------------------------

The patch looks good to me.  The only one minor issue I have is that in checkJobCompleteSuccess
we are still logging at a warn, but we are failing the job, so I would expect that to be logged
at an error instead.  I can fix that when I check it in +1

The test failures look to be caused by a runaway process.
