> 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.
