Sushanth Sowmyan updated HIVE-5048:
-----------------------------------

    Attachment: HIVE-5048.patch.2

Replaced MetaException with IllegalStateException, which is a more accurate representation
for a code block that should never be reached.

> StorageBasedAuthorizationProvider(henceforth referred to as SBAP) is a HiveMetastoreAuthorizationProvider
(henceforth referred to as HMAP, and HiveAuthorizationProvider as HAP) that was introduced
as part of HIVE-3705.
> As long as it's used as a HMAP, i.e. from the metastore-side, as was its initial implementation
intent, everything's great. However, HMAP extends HAP, and there is no reason SBAP shouldn't
be expected to work as a HAP as well. However, it uses a wh variable that is never initialized
if it is called as a HAP, and hence, it will always fail when authorize is called on it.
> We should change SBAP so that it correctly initiazes wh so that it can be run as a HAP
as well.
