> Happens when there's no port information. The way we serialize a YarnURL into
> a string causes the reconstructed path to include the port as -1, which is an
> invalid URL. Path/URL reconstruction from this causes the hostname to be lost.
> This is problematic on clusters running HDFA HA - since there's no host:port
> information, only a service name. I'd imaging it'll be a problem for viewfs
> as well.
