> Federation allows common configuration where namenode specific configuration
> are in the same configuration suffixed by nameservice ID. When namenodes use
> an external storage directory (NFS), in order to make namenodes use different
> directories on the external server, the storage directory configuration must
> also allow specific configuration, using nameservice ID.
