Sean, Most of the times I've found this to be related to two issues:
1. NN and JT have been bound to to localhost or a 127.0.0.1-resolving hostname, leading to the other nodes never being able to connect to its ports, as it never listens over the true network interface. 2. Failure in turning off, or in reconfiguring the firewall.
