Eric Lin created SENTRY-781:
-------------------------------
Summary: User can create/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
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;
