> Currently, by default, Ratis is not enabled on an OM single node cluster. This Jira proposes to change the default single node OM to use Ratis server.
> OM Ratis has been tested extensively and is stable now. To convert a single node cluster to HA, the first step would be to upgrade the cluster to Ratis enabled cluster.
> A non-ratis single node cluster can be upgraded to ratis-enabled single node cluster by just setting the \{{ozone.om.ratis.enable}} config to true and restarting the OM.
