Jesús Camacho Rodríguez updated HIVE-8869:
------------------------------------------
Status: Patch Available (was: In Progress)
The row schema of the lateral views and table scan operators are updated now
after column pruning is applied; thus, the schema conforms to the tuples that
go through the operator, which is important e.g. for HIVE-8435.
As a side effect, the statistics for the lateral views change, so I have
uploaded the changes in those tests files.
[~ashutoshc], can you check it please?
