Jesús Camacho Rodríguez commented on HIVE-8869:
-----------------------------------------------
[~gopalv], the last version of the patch does not change anything for the
schema of the TableScan operator, so nothing will break; it just takes into
account column pruning wrt lateral views.
> RowSchema not updated for some ops when columns are pruned
