discovery.zen.ping.unicast.hostsedit. Out of the box, without any network configuration, Elasticsearch will bind to the available loopback addresses and will scan ports 9300 to 9305 to try to connect to other nodes running on the same server. This provides an auto- clustering experience without having to do any configuration.
Host names are allowed instead of IP addresses (similar to discovery. zen.ping.unicast.hosts ), and IPv6 addresses must be specified in brackets with the port coming after the brackets. It is also possible to add comments to this file. All comments must appear on their lines starting with # (i.e. comments cannot start in the middle of a line)..

Then, to give ES the benefit of the doubt, I service iptables stop, then restart the service on each node. Sometimes the servers see each other and I get a cluster out of elasticsearch, sometimes if not most, the …
