Clean up the scratch.dir (tmp/hive-root) while restarting Hive server.
------------------------------------------------------------------------
Key: HIVE-2181
URL: https://issues.apache.org/jira/browse/HIVE-2181
Project: Hive
Issue Type: Bug
Components: Server Infrastructure
Affects Versions: 0.8.0
Environment: Suse linux, Hadoop 20.1, Hive 0.8
Reporter: sanoj mathew
Priority: Minor
Fix For: 0.8.0
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.
