Todd Lipcon commented on HADOOP-8904:
-------------------------------------
This seems like a bug fix which is relevant for branch-1 as well as newer
branches, not just branch-1-win, right? Is trunk/branch-2 affected?
> Hadoop does not close output file / does not call Mapper.cleanup if
> exception in map

> Find this in Pig unit test TestStore under Windows. There are dangling files
> because map does not close the file when exception happens in map(). In
> Windows, Hadoop will not remove a file if it is not closed. This happens in
> reduce() as well.
