Julian Hyde updated CALCITE-575:
--------------------------------
Summary: Variant of ProjectRemoveRule that considers a project trivial only
if field names are identical (was: Calcite: Project Removal to consider
optional field names)

> Issue Type: Bug
> Reporter: Laljo John Pullokkaran
> Assignee: Laljo John Pullokkaran
> Attachments: CALCITE-575.patch
>
>
> 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.
