Daryn Sharp commented on HDFS-13433:
------------------------------------

This does not appear to be right.  {{testFederationWithoutHa}} illustrates the 
problem.  Just because the NN has an nsId doesn't mean it overrides the 
defaultFS authority.

I'm not aware of the ways the defaultFS is used during NN startup, but it's 
authority should probably be exactly what's sent in the redirect.

> In the following HA+Federated setup with two nameservices ns1 and ns2:
> # ns1 -> namenodes nn1, nn2
> # ns2 -> namenodes nn3, nn4
> # fs.defaultFS is {{hdfs://ns1}}.
> A webhdfs request issued to nn3/nn4 will be routed to ns1. This is because 
> {{setClientNamenodeAddress}} initializes {{NameNode#clientNamenodeAddress}} 
> using fs.defaultFS before the config is overriden.
