Nanda kumar commented on HDDS-298:
----------------------------------
Thanks [~ajayydv] for working on this. The patch looks pretty good to me and
thanks for creating HDDS-311. One minor comment, we should throw an exception
explicitly instead of throwing IllegalArgumentException through
{{Preconditions.checkArgument(dnWithReplicas.size() > 0, "No replicas found for
given container.")}}. We should probably propagate this to the client, it can
be done in a separate jira.
> Implement SCMClientProtocolServer.getContainerWithPipeline for closed
> containers

> As [~ljain] mentioned during the review of HDDS-245
> SCMClientProtocolServer.getContainerWithPipeline doesn't return with good
> data for closed containers. For closed containers we are maintaining the
> datanodes for a containerId in the ContainerStateMap.contReplicaMap. We need
> to create fake Pipeline object on-request and return it for the client to
> locate the right datanodes to download data.
