Ajay Kumar updated HDDS-427:
----------------------------
Description: 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. (was: Callers of an API
ContainerStateMap#getContainerReplicas should be allowed to decide if its
voilaton of some condition (warranting exception) instead of it being implicit
to every caller. ContainerStateMap#getContainerReplicas should return empty
map. Callers can decide if no replicas for given container is a volition of a
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.)
