hanishakoneru commented on issue #948: HDDS-1649. On installSnapshot notification from OM leader, download checkpoint and reload OM state URL: https://github.com/apache/hadoop/pull/948#issuecomment-512981397 > **Question:** > In ShouldInstallSnapshot, it calls getLatestSnapshot() from stateMachineStorage, as we have our own snapshot implementation in stateMachine, do we need to override that method to provide correct snapshotInfo? Or could you provide some info how this works? We do not want the snapshots to be handled via Ratis. When a follower receives installSnaphsot notification, it sends the new loaded DB's snapshot index back to the leader. The leader updates the followers snaphsot index through this. But when Ratis server is starting up, it should be able to determine the latest snapshot index. Otherwise, all the logs will be replayed from the start. I will create a new Jira to address this. Thanks Bharat.
