[jira] [Created] (HDDS-1827) Load Snapshot info when start OM Ratis server

Hanisha Koneru created HDDS-1827:
------------------------------------

             Summary: Load Snapshot info when start OM Ratis server
                 Key: HDDS-1827
                 URL: https://issues.apache.org/jira/browse/HDDS-1827
             Project: Hadoop Distributed Data Store
          Issue Type: Sub-task
            Reporter: Hanisha Koneru
            Assignee: Hanisha Koneru


When Ratis server is starting it looks for the latest snapshot to load it. Even though OM does not save snapshots via Ratis, we need to load the saved snaphsot index into Ratis so that the LogAppender knows to not look for logs before the snapshot index. Otherwise, Ratis will replay the logs from beginning every time it starts up.
