We have start the discussion with Spark guys to open the door for pluggable parser going forward, and some of features we have now would require syntax extension as well, for now, we are ok.

We can add the validation now in carbondata as we control the ddl parsing. But going forward in spark 2.0 we cannot control the ddl parsing so it is not possible to add validations there. So I guess we better stick to the hive behavior to avoid future problems. Regards, Ravindra.
