Carl Steinbach commented on HIVE-3016:
--------------------------------------
bq. Yes, the user can override this property but we don't expect any users to.
You're joking, right?
Also, based on what you have described so far you can accomplish the same
result by running separate metastores.

> Disallow cross database access to tables using Y.T syntax under a specific
> configuration in HiveConf.
> i.e. when hive.error.on.crossdatabaseaccess is set to true, return an error
> when Y.T syntax is used to access tables and Y is not the current database.
> This can be set both via the client and in hive-site.xml, and will default to
> false.
