[jira] [Created] (HAWQ-1249) Don't do ACL checks on segments

Chunling Wang created HAWQ-1249:
-----------------------------------

             Summary: Don't do ACL checks on segments
                 Key: HAWQ-1249
                 URL: https://issues.apache.org/jira/browse/HAWQ-1249
             Project: Apache HAWQ
          Issue Type: Sub-task
          Components: Security
            Reporter: Chunling Wang
            Assignee: Ed Espino


HAWQ does ACL checks on segments, which we think is not necessary for QE because there is no catalog data on segments. Even a hacker can connect to a segdb with GP_ROLE_EXECUTE, he can not do any queries while he can do on Greenplum for there is catalog data on segments. Further more, in ranger checks, if all segments do same checks as master with RPS, it costs a lot and effects the performance.
