Aihua Xu commented on HIVE-10752:
---------------------------------
[~mithun] What the patch does is to enable the optimization (for column based
table retrieval) and then disable it (equivalent to revert IVE-5193), so there
will be no optimization. It's better to revert HIVE-5193 to unblock the
customer and rework on it since such optimization is reasonable for performance
reason.
