Hi guys

I am not getting the expected result from my authorization settings

I am evaluating Hive0.10.0+121

mysql> select * from hive.ROLES;
+---------+-------------+------------+-----------+
| ROLE_ID | CREATE_TIME | OWNER_NAME | ROLE_NAME |
+---------+-------------+------------+-----------+
|       6 |  1376704610 | NULL       | sas_role  |

My settings are as follows.
