      Description

      DecommissionManager is capable of transitioning multiple DataNodes to Decommission/Maintenance states. Current tests under TestDecommission and TestMaintenanceState only request for one DataNode for Decommission/Maintenance. Better if we can simulate real world cases whereby multiple DataNodes can be taken out of service and verify the resulting block replication factor for the files.
