Hmm, yes, actually I don't think I actually understand the issue. Basically as I understand it we do InetAddress.getLocalHost.getHostAddress which on AWS picks the wrong hostname/ip and then the producer can't connect. People eventually find this FAQ, but I was hoping there was a more automatic way since everyone is on AWS these days. Maybe getCanonicalHostName would fix it?
