Nanda kumar commented on HDDS-400:
----------------------------------
Thanks [~elek] for the patch. I agree with [~ajayydv] on this. Instead of
iterating through all the containers from the report, we can handle this in
{{DeadNodeHandler}}. We are already removing the replica from
{{containerStateManager}}, we just have to emit
{{SCMEvents.REPLICATE_CONTAINER}} event if existingReplicas doesn't match with
expectedReplicas.
> Check global replication state of the reported containers on SCM

> Current container replication handler compare the reported containers with
> the previous report. It handles over an under replicated state.
> But there is no logic to check the cluster-wide replication count. If a node
> is went down it won't be detected.
> For the sake of simplicity I would add this check to the
> ContainerReportHandler (as of now). So all the reported container should have
> enough replicas.
> We can check the performance implication with genesis, but as a first
> implementation I think it could be good enough.
