> Key: RANGER-3472
> URL: https://issues.apache.org/jira/browse/RANGER-3472
> Project: Ranger
> Issue Type: Bug
> Components: Ranger
> Affects Versions: 2.1.0
> Reporter: Xuze Yang
> Priority: Major
>
> In our production environment, we happen to find that two policies exist with
> the same resources.In this case, when we want to modify either policy, ranger
> doesn't allow this operation and throws message like "*Error Code : 3010
> Another policy already exists for matching resource: policy-name=[hhh9],
> service=[default-Hdfs]*".
> I go through the source code about create policy, find that the
> createPolicy() in class ServiceREST is not thread safe. When we create
> policies concurrently, we may create several same resource's policies.
