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.
