--------------------------------------
Doc done (please review): *hive.scratch.dir.permission* is documented in the
wiki now.
* [AdminManual Configuration -- Configuration Variables |
https://cwiki.apache.org/confluence/display/Hive/AdminManual+Configuration#AdminManualConfiguration-ConfigurationVariables]
* [Configuration Properties -- hive.scratch.dir.permission |
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-hive.scratch.dir.permission]
By the way, the parameter name omits ".exec." so it doesn't match similar
parameters.

> The hive.exec.scratchdir defaults to /tmp/hive-$\{user.name\}, but when Hive
> creates this directory it doesn't set any explicit permission on it. This
> means if you have the default HDFS umask setting of 022, then these
> directories end up being world readable. These permissions also get applied
> to the staging directories and their files, thus leaving inter-stage data
> world readable.
> This can cause a potential leak of data especially when operating on a
> Kerberos enabled cluster. Hive should probably default these directories to
> only be readable by the owner.
