--------------------------------------

Hi [~stigahuang], sorry for the late response. I think we could close this JIRA.

There are still some follow-up works to this JIRA, but those would require the 
support from Ranger's API's, which is not yet in place.
 # https://issues.apache.org/jira/browse/RANGER-3145 (Dropping a role that is 
still associated with privileges).
 # https://issues.apache.org/jira/browse/RANGER-3150 (Displaying all the 
privileges granted to a specified role).

> Add support for role-related statements

> After IMPALA-9708, we dropped the support for Sentry, an authorization 
> service providing role-based authorization. Since then Impala lacks support 
> for role-based authorization.
> On the other hand, after RANGER-2425, Ranger added APIs for role-related SQL 
> statements. It would be nice to enable role-related SQL statements in Impala 
> with Ranger being the authorization provider so that users that were using 
> Sentry as the authorization provider could still be using Impala if 
> role-based authorization is required.
