I committed the patch to trunk. Could you please submit a patch for the 0.16 branch. This one doesn't apply cleanly. Thanks!

> Until 0.16.0 the value of the getOutputPath() method, if queried within a task, pointed to the part file assigned to the task. 
> For example: /user/foo/myoutput/part_00000
> In 0.16.1, now it returns an internal hadoop for the task output temporary location.
> For the above example: /user/foo/myoutput/_temporary/part_00000
> This change breaks applications that use the getOutputPath() to compute other directories.
> IMO, this has always being broken, Hadoop should not change the values of properties injected by the client, instead it should use private properties or internal helper methods.
