Manoj Govindassamy updated HDFS-11378:

Attachment: HDFS-11378.01.patch
Attached v01 patch to address the following
* A new method {{takeNodeOutofService}} in AdminStatesBaseTest to take in a
list of DataNodeUUIDs for decommission/maintenance operations
* New test in {{TestDecommission}} to invoke takeNodeOutofService with multiple
DNs at the same time, verify the replication factor after decommission
* New test in {{TestMaintenanceState}} to invoke takeNodeOutofService with
multiple DNs at the same time, verify the replication factor before and after
maintenance operation
[~eddyxu], [~mingma], can you please take a look at the patch ? Thanks.
