Does the namenode log contain any entries for the datanode you are trying to
start?

Strange thing is the datanode in the remote location has a log zero bytes.
So nothing there.
Its strange it is like the master does and ssh, login, and then attempts to
start it but nothing. Maybe there is a timeout?
