To roll back the Oozie service, you must restore the Oozie database. If the cluster is kerberized and Oozie is in HA mode then you must manually regenerate the oozie.ha.keytab if you have not already done so.

  • Start Oozie in Ambari UI.

    It is needed to re-generate the oozie.ha.keytab file using the spnego.service.keytab files from the Oozie server hosts and from the Oozie load balancer host and then distribute the generated oozie.ha.keytab onto the respective Oozie hosts. In order to achieve this, follow the steps listed in this website.

  • Restart Oozie.
