Subject [jira] Commented: (HADOOP-3150) Move task file promotion into the task
Date Mon, 21 Jul 2008 14:29:31 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-3150?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12615257#action_12615257
] 

Owen O'Malley commented on HADOOP-3150:
---------------------------------------

No, I wouldn't. Partially for backwards compatibility and partially because the FileOutputCommitter
has a more general interface that takes a path. I suggest:

When a FileOutputFormat is configured, get the output directory and the OutputCommitter. If
the OutputCommitter is a FileOutputCommitter, call setWorkOutputPath with the configuration
and the result of FileOutputPath.getWorkPath(FileOutputFormat.getOutputPath(conf)). Otherwise,
set the work path to the getOutputPath.
