Enabling Oozie High Availability
You must select the host on which to install the additional Oozie server and specify the required property values to install Oozie High Availability (HA).
- In the Cloudera Manager Admin Console, go to the Oozie service.
- Select to see eligible Oozie server hosts. The host running the current Oozie server is not eligible.
- Select the host on which to install an additional Oozie server and click Continue.
- Update the following fields for the Oozie load balancer:
- HTTP Port
- HTTPS Port
- Click Continue.
Cloudera Manager stops the Oozie servers, adds another Oozie server, initializes the Oozie server High Availability state in ZooKeeper, configures Hue to reference the Oozie load balancer, and restarts the Oozie servers and dependent services. In addition, Cloudera Manager generates Kerberos credentials for the new Oozie server and regenerates credentials for existing servers.
