             Summary: Remove self node from the resourceTrie only if it has no 
children, no evaluators and no wildcard-evaluators
                 Key: RANGER-4966
                 URL: https://issues.apache.org/jira/browse/RANGER-4966
             Project: Ranger
          Issue Type: Bug
          Components: Ranger
            Reporter: Abhay Kulkarni
            Assignee: Abhay Kulkarni


If the policy-deltas are enabled, then when two policies have a common subset 
of resources and are defined on same user (or subset of users, through groups 
or direct users), if one of these policies is modified (on anything: name, 
resource, user), it is the only one in effect during access evaluation. Until a 
restart of the underlying service. 

The underlying cause is a ResourceTrie node referring to modified 
policy-evaluator is removed even when it contains wildcard-evaluator(s).
