Arjun Mishra resolved SENTRY-781.
---------------------------------
Resolution: Duplicate
Resolved with SENTRY-2240
> User can run function under a database that he/she has no access
> ----------------------------------------------------------------
>
> Key: SENTRY-781
> URL: https://issues.apache.org/jira/browse/SENTRY-781
> Project: Sentry
> Issue Type: Bug
> Components: Hive Plugin
> Affects Versions: 1.4.0
> Reporter: Eric Lin
> Assignee: Arjun Mishra
> Priority: Minor
>
> 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:
> {code}
> +----------------+--+
> | database_name |
> +----------------+--+
> | default |
> +----------------+--+
> {code}
> However, this role can do the following two things:
> {code}
> 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)
> {code}
> The jar file has been loaded into aux directory for Hive.
> {code}
> 0: jdbc:hive2://10.17.74.148:10000/default> select udf_test.upper_test(code)
> from sample_07 limit 10;
