Fredy Wijaya commented on IMPALA-8531:
--------------------------------------
The check is there for a reason to make sure typos don't go unnoticed. Sentry
doesn't throw an exception when deleting a privilege that does not exist. This
can be bad for user experience. I also believe that we shouldn't use Impala as
a generic Sentry client. IMO, this is something that should be handled by
Sentry administrative tools, e.g. Sentry CLI.

> Project: IMPALA
> Issue Type: Bug
> Components: Catalog, Frontend
> Reporter: Arjun Mishra
> Priority: Major
>
> In sentry we have a property which allows users to drop tables/databases
> without dropping the associated privileges. This leads to orphan privileges
> however this is desired in some customer use case.
> In Impala we cannot revoke sentry privileges for non-existent tables (this
> works with non-existent databases)
