Namit Jain commented on HIVE-3720:
----------------------------------

[~shreepadma], how is it different from the current hive authorization model ?
Is the proposed functionality a superset of the existing one ?
If yes, can you mark in the wiki, what has been already implemented ?
                
> Expand and standardize authorization in Hive

> The existing implementation of authorization in Hive is not complete. 
> Additionally the existing implementation has security holes. This JIRA is an 
> umbrella JIRA  for a) extending authorization to all SQL operations and 
> direct metadata operations, and b) standardizing the authorization model and 
> its semantics to mirror that of MySQL as closely as possible.
