Lenni Kuff commented on SENTRY-855:
-----------------------------------
I agree - this would require updating the SQL support in Hive I believe to
fully support this functionality. If Impala wanted to use this it would require
Impala-side changes as well. Perhaps file JIRAs for those projects to get this
support added - after that support is in place we could update the Sentry Hive
binding to take advantage of it.
> support DROP ROLE IF EXISTS or CREATE ROLE IF NOT EXISTS

> For drop database/table/view, we support syntax such as,

> Only for role, there is no support for IF EXISTS,
> We might need to consider to add it.
