    Description

      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.
