--------------------------------------

             Summary: Increment service-specific policy and tag versions after update transaction
is committed
                 Key: RANGER-2186
                 URL: https://issues.apache.org/jira/browse/RANGER-2186
             Project: Ranger
          Issue Type: Bug
          Components: Ranger
    Affects Versions: master
            Reporter: Abhay Kulkarni
            Assignee: Abhay Kulkarni
             Fix For: master


Policy updates to different policies within a service, when successful, update the service's
policy version. If the update transactions are concurrent, and executed on different ranger-admin
servers (in HA configuration), then it is possible that policy-version of the transaction
that commits later overwrites policy-version of earlier transaction, effectively losing track
of the first change.

If policy-version is updated after update to policy is committed, then the window of such
loss is greatly reduced.

Similar considerations apply for tag updates.
