Review request for Ambari, Attila Magyar, Balázs Bence Sári, DIPAYAN BHOWMICK,
Eugene Chekanskiy, Gaurav Nagar, Laszlo Puskas, and Sebastian Toader.
Bugs: AMBARI-20462
https://issues.apache.org/jira/browse/AMBARI-20462
Repository: ambari
Description
-------
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:
```
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)
```
- 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.
