> not gated to use any of the authorization model which HiveMetastore provides.

> 1. Login to Hue => create the first user called "admin" and provide a
> password Access the Hive Editor
> 2. On the SQL section on the left under Databases you should see default and
> database1 listed. Click on database1
> 3. As you can see a table called table1 is listed => this should not be
> possible as our admin user has no HDFS grants on /datasets/database1
> 4. run from the Hive editor the following query SHOW TABLES; The output shows
> a Permission denied error => this is the expected behavior
