radford nguyen commented on IMPALA-8280:
----------------------------------------
It appears that the only way to get the policies from Ranger is to go through
the REST API *service/public/v2/api/service/\{service-name}/policy*.
Hive-Ranger gets policies by querying HMS, which we have been told is actually
the incorrect way to do it, as per RANGER-2367.
We will need to wait for that ticket to complete in order to implement {{show
grant}} in the same way as Hive.
