Summary: Views : "cannot load permission" error when accessing the ambari view
Key: AMBARI-11183
URL: https://issues.apache.org/jira/browse/AMBARI-11183
Project: Ambari
Issue Type: Task
Reporter: Tom Beerbower
Assignee: Tom Beerbower
Fix For: 2.1.0
"cannot load permission" error when accessing the ambari view
The problem is that there are privileges in the DB that do not have an associated resource.
To reproduce:
Delete jars of views which have an instance left in ambari, from /var/lib/ambari-server/resources/views/ and restart ambari.
{code}
mysql> select * from adminprivilege left join adminresource on adminprivilege.resource_id = adminresource.resource_id where
adminresource.resource_id is null;
+--------------+---------------+-------------+--------------+-------------+------------------+
| privilege_id | permission_id | resource_id | principal_id | resource_id | resource_type_id |
+--------------+---------------+-------------+--------------+-------------+------------------+
| 46 | 4 | 7 | 9 | NULL | NULL |
| 47 | 4 | 7 | 1003 | NULL | NULL |
+--------------+---------------+-------------+--------------+-------------+------------------+
2 rows in set (0.00 sec)
mysql> select * from adminresource;
+-------------+------------------+
| resource_id | resource_type_id |
+-------------+------------------+
| 1 | 1 |
| 3 | 2 |
| 4 | 5 |
| 8 | 12 |
| 6 | 8 |
+-------------+------------------+
5 rows in set (0.00 sec)
This results in a NPE in line where getResource() is empty.
switch (privilegeEntity.getResource().getResourceType().getId()) {
Verified this with Alejandro Fernandez and the solution is basically to remove the privilege that does not have an corresponding resource. This can be removed by running
delete from adminprivilege where privilege_id=46
{code}
