Network setup: Cluster: Why can't name self in list of hosts?

Elastic Stack Elasticsearch
1

On 5.6.4

Why is it that I cannot list each nodes' OWN IP in:

discovery.zen.ping.unicast.hosts:

?

If I do this, (e.g. give every node in cluster same entry for "discovery.zen.ping.unicast.hosts: " ), then the cluster comes up red.

Why is ES so finnicky about this? (and forces me to script more for the setup)

It shouldn't be a problem.

Perhaps if you share some logs we can check what is happening?

I am happy to share logs, but they don't say anything... (they show no errors)

The situation is:

Two ES servers, intent is to cluster them. Machines are: 192.168.10.33 and 192.168.10.34

On the .33 system, I can do:

discovery.zen.ping.unicast.hosts: ["192.168.10.34"]

If I do, on both nodes:

discovery.zen.ping.unicast.hosts: ["192.168.10.33", "192.168.10.34"]

The cluster health is red.

I can only get cluster health to green if .33 points to .34, and .34 points to .33

It would be nice to have a more vanilla way to go.

Open to suggestions!

Right, but they will show something, so it'd be useful :slight_smile:
