CR Hota commented on HDFS-13532:
--------------------------------

Thanks everyone for all the reviews so far.

MoM
 # Everyone tilted towards Approach 1 based on the pros and cons outlined.
 # Anu raised a valid point about multi domain cluster set-ups. He would like 
us to update the document with thoughts on this area. 
 # Inigo felt we should start prototyping approach 1.
 # Brahma also felt Approach 1 would be better.
 # Everyone more or less agreed that Approach 1 is also easy to implement.

Attaching an updated document which contains some initial information around 
multi domain. [~anu] could you please to add more context around it. As of now, 
secured router could facade multiple hdfs clusters that all work on the same 
domain.
