> CALCITE-92 seems to have changed behavior of ProjectRemoveRule to discard
> field names while considering if a project is trivial. Unfortunately they way
> Hive is integrated with Calcite we would need to preserve names.
> This issue would go away once Calcite Operators get converted to Hive
> Operators as opposed to Hive AST.
