[jira] [Created] (RANGER-2878) Add read write lock to RangerResourceTrie

star created RANGER-2878:
----------------------------

             Summary: Add read write lock to RangerResourceTrie
                 Key: RANGER-2878
                 URL: https://issues.apache.org/jira/browse/RANGER-2878
             Project: Ranger
          Issue Type: Bug
          Components: plugins
    Affects Versions: 2.0.0
            Reporter: star
            Assignee: star


Current incremental policy update mechanism may cause issues in two cases.

      1. When policy is updated, it is consist of two operations: delete then add. Policy is temporarily unavailable after delete and before add operation. It may cause task failure.

      2. RangerResourceTrie is also updated when matching policies (ref RANGER-2760 and RANGER-2761). Without read write lock, it will lead to chaos and inaccurate result.
