Dear Community,
I want to put in place a kind of redundant loadbalancing setup with 2 ElasticSearch nodes + 2 Kibana Nodes with Elasticsearch Coordinated Only node role.
Here a picture of the setup
I will give you my configuration for each nodes :
elastic-01:
```
cluster.name: mycluster
node.name: elastic-01
network.host: 10.10.68.24
http.port: 9200
discovery.zen.ping.unicast.hosts: ["elastic-01", "elastic-02", "kibana-01", "kibana-02"]
discovery.zen.master_election.ignore_non_master_pings: true
elastic-02:
cluster.name: mycluster
node.name: elastic-02
network.host: 10.10.68.25
http.port: 9200
discovery.zen.ping.unicast.hosts: ["elastic-01", "elastic-02", "kibana-01", "kibana-02"]
discovery.zen.master_election.ignore_non_master_pings: true
```
kibana-01:
```
cluster.name: mycluster
node.master: false
node.data: false
node.ingest: false
search.remote.connect: false
network.host: localhost
http.port: 9200
transport.host: 10.10.68.25
transport.tcp.port: 9300
```
kibana-02:
```
cluster.name: mycluster
node.master: false
node.data: false
node.ingest: false
search.remote.connect: false
network.host: localhost
http.port: 9200
transport.host: 10.10.68.26
transport.tcp.port: 9300
```
It seems that when I browse from [http://kibana-01:5601/](http://kibana-01:5601/) i have the following error :
```
plugin:elasticsearch@6.2.3 Service Unavailable
```
The same from the [http://kibana-02:5601](http://kibana-02:5601).
The elasticsearch logs from the Coordinated Only Nodes :
```
[2018-04-20T13:36:02,145][WARN][o.e.d.z.ZenDiscovery] [zxSDt-c] not enough master nodes discovered during pinging (found [[]], but needed [-1]), pinging again
```
It seems that the coordinated only nodes are not seing the other elasticsearch nodes..
Maybe you have an idea on what is wrong with my setup.
Best Regards, Edouard.

ALL nodes need to know how to connect to the other nodes, so you need to add this also on the coordinating nodes.
If you have 2 nodes that are master-eligible, you should also set `minimum_master_nodes` to 2 as per [these guidelines](https://www.elastic.co/guide/en/elasticsearch/reference/6.2/modules-node.html#split-brain).
