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

Carl Steinbach commented on HIVE-1187:
--------------------------------------

@Ashutosh: No, I don't think this feature has been implemented. This ticket was resolved as
a duplicate of HIVE-967, but I don't think there has been any work on 967 since then.

> 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.
