Amareshwari Sriramadasu commented on MAPREDUCE-1662:
----------------------------------------------------
bq. -1 tests included.
No new tests added because patch removes dead code.
bq. -1 core tests.
The test failure TestMapReduceLazyOutput.testLazyOutput is not related to the patch. The test
failed because of ZipExceptions (MAPREDUCE-1642).
The same test passed on my machine.
> TaskRunner.prepare() and close() can be removed

> 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.
