Subject [jira] Created: (HIVE-1187) Implement ddldump utility for Hive Metastore

Implement ddldump utility for Hive Metastore

                 Key: HIVE-1187
                 URL: https://issues.apache.org/jira/browse/HIVE-1187
             Project: Hadoop Hive
          Issue Type: New Feature
          Components: Metastore
    Affects Versions: 0.6.0
            Reporter: Carl Steinbach
            Assignee: Carl Steinbach

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.
