Description

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.
