Hortonworks provides a set of connectors that enable Storm developers to quickly write streaming data to a Hadoop cluster. These connectors are located at /usr/lib/storm/contrib. Each contains a .jar file containing the connector's packaged classes and dependencies, and another .jar file with javadoc reference documentation.

This chapter describes how to use several connectors, and how to configure connectors in a Kerberos-enabled cluster. For a more thorough discussion of Apache Storm connectors and APIs, see the Apache Storm documentation for your version of Storm.
