             Summary: SCMContainerPlacementRackAware should try to find node on the same rack as second affinity node before fallback
                 Key: HDDS-5697
                 URL: https://issues.apache.org/jira/browse/HDDS-5697
             Project: Apache Ozone
          Issue Type: Bug
            Reporter: Sammi Chen
            Assignee: Sammi Chen


If an under replicated container has 2 replicas, SCMContainerPlacementRackAware only chooses the node on the rack of  first replica, if no available node found, it just fallback to ignore the rack topology.   In the case, SCMContainerPlacementRackAware should try the second replica too before it fallback.
