> In Kubernetes clusters redundance if very important. Using more than one instance of OM or SCM results in multiple errors. In my opinion HA modes of SCM and OM should be enabled as described [https://ozone.apache.org/docs/current/feature/om-ha.html] and [https://ozone.apache.org/docs/current/feature/scm-ha.html |https://ozone.apache.org/docs/current/feature/scm-ha.html]when more then one replica of OM or SCM is configured. But I would like to discuss if this is the correct way or if there are other solutions for multiple nodes in Kubernetes clusters.
