[jira] [Created] (HDDS-3509) Closing container with unhealthy replica on open pipeline

Nanda kumar created HDDS-3509:
---------------------------------

             Summary: Closing container with unhealthy replica on open pipeline
                 Key: HDDS-3509
                 URL: https://issues.apache.org/jira/browse/HDDS-3509
             Project: Hadoop Distributed Data Store
          Issue Type: Bug
          Components: Ozone Datanode
    Affects Versions: 0.5.0
            Reporter: Nanda kumar
            Assignee: Nanda kumar


When a container replica of an OPEN container is marked as UNHEALTHY, SCM tries to close the container.
If the pipeline is still healthy, we try to close the container via Ratis. 

We could run into a scenario where the datanode which marked the container replica as UNHEALTHY is the pipeline leader. In such case that datanode (leader) should process the close container command even though the container replica is in UNHEALTHY state.
