Ashutosh Chauhan commented on HIVE-3016:
----------------------------------------

I concur with Ed & Carl. Proposed solution is not the appropriate one for the described problem. Whole point of auth system is to address such use-cases. If auth system is lacking in some ways to address the use case, we shall strive to improve it.

> 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.
