Subject [jira] Commented: (MAPREDUCE-947) OutputCommitter should have an abortJob method
Date Wed, 14 Oct 2009 05:32:31 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-947?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12765404#action_12765404
] 

Amar Kamat commented on MAPREDUCE-947:
--------------------------------------

bq.  This is insync with the apis for tasks i.e abortTask() and cleanupTask()
For the task its commitTask(), abortTask() and setupTask(). For a job, cleanupJob() already
exists and I havent changed that for backward compatibility. May be we can rename cleanupJob()
to commitJob() in a new jira.

> The OutputCommitter needs an abortJob method to clean up from failed jobs. Currently
there is no way to distinguish between failed or succeeded jobs, making it impossible to write
output promotion code.
