    Description

      HIVE-8454 showed some test failures related to lateral view stats showing data size as 0. The reason for that is column expression map for LateralViewForwardOperator is not populated which results column lists becoming empty. As a result neededColumns and referencedColumns will be empty. Hence no column stats will be fetched making data size as 0.
