Mukul Kumar Singh commented on HDDS-298:
----------------------------------------
Thanks for updating the patch and raising the followup jira [~ajayydv]. The
current patch looks really good to me. I have a minor comment on
ContainerMapping:217. Rest the patch looks good to me.
1) ContainerMapping:217.:I feel we should not use the earlier pipeline name
once the container has been closed. so pipeline name can be changed to `String
name = CLOSE_PIPELINE_PREFIX + contInfo.containerID()`;
2) TestContainerMapping:185: there are commented lines in the code
> 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.
