As Oozie becomes a critical component in the Hadoop ecosystem users needs assured availability of the services provided by Oozie. To support this need Oozie should include a new feature to support high availability. This feature needs to take into consideration that Oozie provides RESTful APIs, Java APIs, and a command line API that should all be insensitive to the availability of any specific server or components. At Yahoo! it is not required that there be session fail-over from the client. It is acceptable for the client to reconnect if a session is lost as long as the state data managed by the Oozie service is not lost.
