There is no mapping exist for Unhealthy state in Datanode for containers to
LifecycleState of containers in SCM. Hence, the container report publisher
fails with Invalid container state exception.
A container is marked unhealthy in Datanode only if a certain write transaction
fails, so that successive updates get rejected and a close container action is
initiated to SCM to close the container. For all practical cases, a container
in unhealthy state can also be mapped to a container in closing state in SCM.
