Description

When user has no access to a particular database, he/she is still able to create permanent function in it.

For example, a role has no access to database "udf_test", as show by the "show databases" command:

+----------------+--+
| database_name  |
+----------------+--+
| default        |
+----------------+--+

However, this role can do the following two things:

0: jdbc:hive2://10.17.74.148:10000/default> create function udf_test.upper_test as 'com.elin.ToUpper';
No rows affected (0.216 seconds)

The jar file has been loaded into aux directory for Hive.

0: jdbc:hive2://10.17.74.148:10000/default> select udf_test.upper_test(code) from sample_07 limit 10;

This violates the sentry permission mechanism.
