Amareshwari Sriramadasu updated MAPREDUCE-1662: ----------------------------------------------- Status: Patch Available (was: Open) > TaskRunner.prepare() and close() can be removed > ----------------------------------------------- > > Key: MAPREDUCE-1662 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-1662 > Project: Hadoop Map/Reduce > Issue Type: Bug > Components: tasktracker > Affects Versions: 0.22.0 > Reporter: Amareshwari Sriramadasu > Fix For: 0.22.0 > > Attachments: patch-1662.txt > > > TaskRunner.prepare() and close() methods call only mapOutputFile.removeAll(). > The removeAll() call is a always a no-op in prepare(), because the directory > is always empty during start up of the task. The removeAll() call in close() > is useless, because it is followed by a attempt directory cleanup. Since the > map output files are in attempt directory, the call to close() is useless. > After MAPREDUCE-842, these calls are under TaskTracker space, passing the > wrong conf. Now, the calls do not make sense at all. > I think we can remove the methods. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
