> With HDFS-11058, Df command will work well with ViewFileSystem. federated cluster can be backed up several NameServers, with each managing their own NameSpaces. Even when some of the NameServers are down, the Federated cluster will continue to work well for the NameServers that are alive. 
> But {{hadoop fs -df}} command when run against the Federated cluster expects all the backing NameServers to be up and running. Else, the command errors out with exception. 
> Would be preferable to have the federated cluster commands highly available to match the NameSpace partition availability.
