      Description

      A previous Jira, TRAFODION-2498, added support to pass through some DDL commands to hive API. It was done via:  process hive statement 'hive-ddl-command' syntax. The supplied command was passed in as-is to the underlying interface.

      This current Jira is to add support to directly perform DDL operations on Hive objects without having to use 'process hive statement'. 

        Example:  create table hive.hive.t (...)  ...

        or:     alter table hive.hivesch.t ....

      With this enhancement, Hive objects will be treated similar to traf objects while performing DDL operations. Things like registration/unregistration in traf MD, query invalidation, cleanup, etc will be done automatically.

      A detailed spec/note will be added later.
