             Summary: UNHEALTHY replicas will not contribute to sufficient replication in RatisContainerReplicaCount
                 Key: HDDS-7804
                 URL: https://issues.apache.org/jira/browse/HDDS-7804
             Project: Apache Ozone
          Issue Type: Sub-task
          Components: SCM
    Affects Versions: 1.3.0
            Reporter: Siddhant Sangwan
            Assignee: Siddhant Sangwan
             Fix For: 1.4.0


As of HDDS-6447, RatisContainerReplicaCount considers only replicas that match the container state when counting sufficient replication.

Current Behaviour -
Example 1:
Container State: CLOSED
Replicas: CLOSED, CLOSED, CLOSING.
RatisContainerReplicaCount#isSufficientlyReplicated will return false for this container. 

Example 2:
Container State: CLOSED
Replicas: CLOSED, CLOSED, UNHEALTHY.
RatisContainerReplicaCount#isSufficientlyReplicated will return false for this container. 

This behaviour makes it simpler to work with different cases in the Legacy Replication Manager. However, we will change this behaviour for the new RM while ensuring Legacy still works as expected.

This jira proposes excluding only replicas with UNHEALTHY state when calculating sufficient replication. Example 1 will return true, while 2 will return false.
