Nanda kumar commented on HDDS-23:
---------------------------------

Thanks [~anu] for the review. 
>> we will use this when SCM HA is enabled...
For SCM HA it should be sufficient having {{SCMNodeAddressList}} in the 
response of register command, which is still there.
This jira removes {{SCMNodeAddressList}} from the register request call which 
is sent from datanode to SCM.

> {{SCMNodeAddressList}} in {{SCMRegisterRequestProto}} is not used by SCM and 
> it's not necessary to send it in register call of datanode. 
> {{SCMNodeAddressList}} can be removed from {{SCMRegisterRequestProto}}.
