> Key: AMBARI-20462
> URL: https://issues.apache.org/jira/browse/AMBARI-20462
> Project: Ambari
> Issue Type: Bug
> Components: ambari-server
> Affects Versions: 2.5.0
> Reporter: Vivek Sharma
> Assignee: Robert Levas
> Priority: Critical
> Labels: system_test

>
> When I create a new user from Ambari UI and let’s say give him ‘Cluster User’
> role; later go to Users page it shows the permissions as seen in the
> screenshot
> The UI display is fine, however when I make an API call like below
> /api/v1/users/tom/privileges?fields=*
>
> It shows three entries for each auto_<view>_instance privilege. As an
> example: for ‘AUTO_FILES_INSTANCE’ I see three entries like:
> api/v1/users/tom/privileges/6
> api/v1/users/tom/privileges/56
> api/v1/users/tom/privileges/106
>
> and so on, so we have 16 entries (One for Cluster.User + 3 * privileges for
> each of five View instances)
>
> The same behavior is seen for groups too like:
> /api/v1/groups/gp1/privileges?fields=*
> *Example*
> It is expected that only one of the following rows exists:
> {noformat}
> ambaricustom=> select * from adminprivilege where privilege_id in (6, 56,
> 106);
> privilege_id | permission_id | resource_id | principal_id
> --------------+---------------+-------------+--------------
> 6 | 4 | 54 | 8
> 56 | 4 | 54 | 8
> 106 | 4 | 54 | 8
> (3 rows)
> {noformat}
>
> * permission_id (4): VIEW.USER
> * resource_id (54): AUTO_FILES_INSTANCE
> * principal_id (8): CLUSTER.USER
> *Cause*
> When Ambari server restarts, it installs the automatically created view
> instances without first checking to see if they have been previously created.
> Each restart of Ambari server will create a new set of duplicated records.
