Ming Ma commented on HDFS-9391:
-------------------------------

Thanks Manoj. Yep let us keep the existing property as Eddy mentioned.

* In {{getMaintenanceOnlyReplicas}} the check of {{if 
(!isDecommissionInProgress() && !isEnteringMaintenance())}} only needs to check 
for maintenance part.
* It seems you will need to add {{<li class="dfshealth-node-icon 
dfshealth-node-down-maintenance">In Maintenance &amp; dead</li>}} to match the 
addition of {{nodes[i].state = "down-maintenance";}}.
* For the {{EnteringMaintenanceNodes}} page, it uses 
{{maintenanceOnlyReplicas}} to describe {{Blocks with no live replicas}}. 
Should we use {{OutOfServiceOnlyReplicas}}?
