Subject [jira] [Commented] (HIVE-335) External Tables should have the option to be marked Read Only

is small enough and Apache Ranger rules allows data copy, the most naive way is to duplicate
that dataset as a workaround to this problem.

should still be allowed.
> This will enable hive to "play well" with external data stores other than hdfs where
data should be non-maleable.
> I'd recomend the following syntax, which applies ONLY to external tables:
