[jira] [Created] (TRAFODION-3086) Traf support for DDL operations directly on Hive objects

Anoop Sharma created TRAFODION-3086:
---------------------------------------

             Summary: Traf support for DDL operations directly on Hive objects  
                 Key: TRAFODION-3086
                 URL: https://issues.apache.org/jira/browse/TRAFODION-3086
             Project: Apache Trafodion
          Issue Type: New Feature
            Reporter: Anoop Sharma
            Assignee: Anoop Sharma


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.
