Subject [jira] Commented: (HADOOP-3150) Move task file promotion into the task
Date Fri, 04 Jul 2008 06:43:49 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-3150?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12610465#action_12610465
] 

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

Rather that use HADOOP-3227, I think it would be better to extend HADOOP-3149 to have a method
to get a file handle. Something like:

{code}
  FSDataOutputStream createSideFile(String name) throws IOException;
{code}

and the file will be managed by the output format, reside in the output dir, be named relative
to the task, etc.

Does that sound reasonable?

into the output format.
