> hive doesn't depend on hadoop job output folder. it produces output
> exclusively via side effect folders. we should use an outputformat that can
> request hadoop skip cleanup/setup. this could be nulloutputformat (unless
> there are any objections in hadoop to changing nulloutputformat behavior).
> as a small side effect, it also avoids some totally unnecessary hdfs file
> creates and deletes in hdfs.
