It's not the clustername. The unit test works if I force the node to use 
another port...

            Settings settings = 
ImmutableSettings.settingsBuilder().put("cluster.name", "elasticsearch")
                    .put("network.publish_host", 
"192.168.2.15").put("network.bind_host", "192.168.2.15")
                    .put("transport.tcp.port", 
9301).put("transport.publish_port", 9301).build();

But by default transport.tcp.port is range 9300-9400, but it always picks 
both for the first and the second client always 9300.

Shouldn't the port clash be discovered automatically?

grtz, Koen
