Ashutosh Chauhan commented on HIVE-6122:
----------------------------------------

Are you concerned about backward-compat? That we show all privileges for user with {{ show grant user hive_test_user }} as oppose to only user-level earlier. Than in HIVE-5928 a new plugin api is implemented, so we can make backward incompatible change on new api, instead of modifying behavior for existing syntax of old api. Also, HIVE-5929 has impl of that api.
In other words, only with {{ set hive.security.authorization.manager=org.apache.hadoop.hive.ql.security.authorization.plugin.sqlstd.SQLStdHiveAuthorizerFactory }}  {{ show grant user hive_test_user }} will show all privileges for user, otherwise old behavior.

> Currently, hive shows privileges owned by a principal. Reverse API is also needed, which shows all principals for a resource. 
> {noformat}
> show grant user hive_test_user on database default;
> show grant user hive_test_user on table dummy;
> show grant user hive_test_user on all;
> {noformat}
