Anu Engineer commented on HDDS-427:
-----------------------------------
Just so that we are on the same page, I made very same comments on HDDS-351. So
I am little surprised that this patch is coming back.
> For containers with no replica ContainerStateMap#getContainerReplicas should
> return empty map

> Callers of API ContainerStateMap#getContainerReplicas should be allowed to
> decide if its violation of some condition (when there are no replicas,
> warranting exception) instead of it being implicit to every caller. Instead
> ContainerStateMap#getContainerReplicas should return empty map for no
> replicas. Callers can decide if no replicas for given container is a volition
> of business condition. Throwing exception in this API also results in a
> subtle bug in ContainerReportHandler where exception for one container may
> result in whole container list being skipped.
