Subject [jira] Commented: (HADOOP-3150) Move task file promotion into the task
Date Mon, 26 May 2008 19:31:56 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-3150?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12599901#action_12599901
] 

Devaraj Das commented on HADOOP-3150:
-------------------------------------

So maybe we should define a subclass of OutputFormat (so that we don't break existing apps)
called OutputFormatWithCommit and let FileOutputFormat implement that. The place where the
task framework code should invoke the commit can then check whether the outputformat implements
the new OutputFormatWithCommit, and, if so, invoke the commit method.

> We need to move the task file promotion from the JobTracker to the Task and move it down
into the output format.
