             Summary: Optimize the performance of hawq with ranger enabled.
                 Key: HAWQ-1311
                 URL: https://issues.apache.org/jira/browse/HAWQ-1311
             Project: Apache HAWQ
          Issue Type: Sub-task
            Reporter: Hubert Zhang
            Assignee: Ed Espino


There are still more than one ranger plugin server(rps) call for a single query. We need to
first analyse the cost of ranger aclcheck and then using a query level aclcache to minimise
the times of rps call for each query.
