Subject [jira] Updated: (MAPREDUCE-947) OutputCommitter should have an abortJob method
Date Mon, 05 Oct 2009 05:49:31 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-947?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Amar Kamat updated MAPREDUCE-947:
---------------------------------

    Release Note: Introduced abortJob() method in OutputCommitter which will be invoked when
the job fails or is killed. Also a _done file is created in the output folder for successful
jobs while _abort is created for failed/killed jobs.

> 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.
