Edward Capriolo commented on HIVE-1187:
---------------------------------------

+1 Having 'show create table' XXXX'   will be very useful. I always seem to lose those table
definitions.

>             Project: Hadoop Hive
>          Issue Type: New Feature
>          Components: Metastore

> Implement a ddldump utility for the Hive metastore that will generate the QL DDL necessary
to recreate the state of the current metastore on another metastore instance.
> A major use case for this utility is migrating a metastore from one database to another
database, e.g. from an embedded Derby instanced to a MySQL instance.
> The ddldump utility should support the following features:
> * Ability to generate DDL for specific tables or all tables.
> * Ability to specify a table name prefix for the generated DDL, which will be useful
for resolving table name conflicts.
