    Description

      Add the support of column pruning for column oriented table access which was done in HIVE-5193 but was reverted due to the join issue in HIVE-10720.

      In 1.3.0, the patch posted by Viray didn't work, probably due to some jar reference. That seems to get fixed and that patch works in 2.0.0 now.
