--------------------------------------
Doc note: This added configuration parameter *hive.start.cleanup.scratchdir*
to HiveConf.java in release 0.8.1 (not 0.8.0 as indicated in Fix Version).

* [Configuration Properties -- hive.start.cleanup.scratchdir |
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-hive.start.cleanup.scratchdir]

> Now queries leaves the map outputs under scratch.dir after execution. If the

> improved disk usage.
