Community Features

The following features are developed and tested by the community, but are not officially supported by Hortonworks. There are variety of reasons that these features are excluded, including: insufficient reliability or incomplete test case coverage, declaration of non-production readiness by the community at large, feature deviates from Hortonworks best practices, and more. Do not use them in your production environments.
