Thanks,

Upgrading hive 0.6 to 0.7 should be a problem?

Hive 0.7.0 has grant/revoke syntax.

If you are looking for a simple solution in a pre "hadoop security"
world: Recursively  own /user/hive/warehouse by a user different then
the user running queries and enable dfs.permissions. This should
prevent anyone from writing to the files. Although jobs running and
failing will be less then optimal. After a few failures hopefully
users will get the point.
