[jira] [Created] (HDDS-4498) Enable OM Ratis by default

Hanisha Koneru created HDDS-4498:
------------------------------------

             Summary: Enable OM Ratis by default
                 Key: HDDS-4498
                 URL: https://issues.apache.org/jira/browse/HDDS-4498
             Project: Hadoop Distributed Data Store
          Issue Type: Improvement
          Components: OM
            Reporter: Hanisha Koneru
            Assignee: Hanisha Koneru


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.
