                 URL: https://issues.apache.org/jira/browse/HAWQ-1311
             Project: Apache HAWQ
          Issue Type: Sub-task
            Reporter: Hubert Zhang

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.
