> JIRA for tracking work related to Hive/Kudu integration.
> It would be useful to allow Kudu data to be accessible via Hive. This would
> involve creating a Kudu SerDe/StorageHandler and implementing support for
> QUERY and DML commands like SELECT, INSERT, UPDATE, and DELETE. Kudu
> Input/OutputFormats classes already exist. The work can be staged to support
> this functionality incrementally.
