Review request for hive.
Changes
-------
In testcases server startup is removed and added unit tests for
cleanUpScratchDir().
Summary
-------
Now queries leaves the map outputs under scratch.dir after execution. If the
hive server is stopped we need not keep the stopped server's map oputputs. So
whle starting the server we can clear the scratch.dir. This can help in
improved disk usage.
Implemented a cleanup method in HiveServer and it will trigger based on the
property value "hive.start.cleanup.scrachdir"
This addresses bug HIVE-2181.
