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

     [ https://issues.apache.org/jira/browse/RANGER-2878?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

star updated RANGER-2878:
-------------------------
    Description: 
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 operation 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.
