             Summary: For containers with no replica ContainerStateMap#getContainerReplicas should return empty map
                 Key: HDDS-427
                 URL: https://issues.apache.org/jira/browse/HDDS-427
             Project: Hadoop Distributed Data Store
          Issue Type: Improvement
            Reporter: Ajay Kumar


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.
