Ming Ma commented on HDFS-9391:
-------------------------------
Good point. Actually it seems maintenanceOnlyReplicas is the same as
outOfServiceOnlyReplicas in such case. For example, say one replica is
decommissioning and two are entering maintenance, both maintenanceOnlyReplicas
and outOfServiceOnlyReplicas are incremented. In other words,
maintenanceOnlyReplicas isn't strictly "all 3 replicas are maintenance". Maybe
this new definition is more desirable. What do you think?
