Description

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.
