> Project: Hive
> Issue Type: Improvement
> Components: Query Planning
> Reporter: Alexander Pivovarov
> Assignee: Alexander Pivovarov
> Priority: Minor
>
> MapJoinDesc and HashTableSinkDesc are derived from JoinDesc
> HashTableSinkDesc and MapJoinDesc have keyTblDesc field.
> JoinDesc has keyTableDesc field.
> I think HashTableSinkDesc and MapJoinDesc can use superclass (JoinDesc)
> keyTableDesc field instead of defining their own keyTblDesc.
