Have a look at this document oozie and link

You can omit the HA setup steps.

This is actually well explained in the ambari docs. Be sure to add the services extensions to make sure the two servers don't duplicate jobs

Just as some comments: Without Load Balancer Oozie will continue to schedule jobs even if one server is down. But administration (submitting jobs ... ) would require you to point to the surviving oozie.

Also what the documents not describe is how to configure the underlying database in DR, that is your job. Here is an example for Postgres:

However databases like Mysql and Postgres seem to be very stable so making for example Oozie Server HA is much more important than doing that for the underlying database. So you could decide to just backup the database regularly.
