6. Oozie High Availability


This feature is available with HDP 2.2 or later.

To setup high availability for the Oozie service, you can run two or more instances of the Oozie Server component.


The relational database that backs the Oozie Server should also be made highly available using best practices defined for the database system in use and should be done after consultation with your in-house DBA. Using the default installed Derby database instance is not supported with multiple Oozie Server instances and therefore, you must use an existing relational database. When using Derby for the Oozie Server, you will not have an option to add Oozie Server components to your cluster.


High availability for Oozie requires the use of an external Virtual IP Address or Load Balancer to direct traffic to the Oozie servers.
