Hive should use NullOutputFormat for hadoop jobs
------------------------------------------------
Key: HIVE-1355
URL: https://issues.apache.org/jira/browse/HIVE-1355
Project: Hadoop Hive
Issue Type: Bug
Components: Query Processor
Reporter: Joydeep Sen Sarma
see https://issues.apache.org/jira/browse/MAPREDUCE-1802
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.
