Description

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.
