Andrew Wang commented on HDFS-5250:
-----------------------------------

Hi Vrushali,

ViewFileSystem is a purely client-side abstraction, each client can have their 
own viewfs mount points, and the federated namenodes are unaware of where they 
are mounted as well as the list of other namenodes/mount points.

I think something like this is only really possible with a single sharded 
namespace, not the client-side mount table that ViewFileSystem provides. Maybe 
I missed something, but we should probably close this JIRA as wontfix.
