> Adding/Updating mount points right now is only a router action without
> validation in the downstream namenodes for the destination files/directories.
> In practice we have set up the dangling mount points and when clients call
> listStatus they would get the file returned, but then if they try to access
> the file FileNotFoundException would be thrown out.
