What Host IP should I use to bind my 2 nodes with the same cluster.

Given this configuration:

Node1:  
cluster.name: sql  
node.name: engineering  
node.master: true  
node.data: true  
network.host: 127.0.0.3  
transport.tcp.port: 9300-9400  
http.port: 9200  
discovery.zen.ping.multicast.enabled: false  
discovery.zen.ping.unicast.hosts: ["127.0.0.3", "127.0.0.2"]  
index.number\_of\_shards: 2  
index.number\_of\_replicas: 1

Node2:  
cluster.name: sql  
node.name: team  
node.master: false  
node.data: true  
network.host: 192.168.0.1  
http.port: 9200  
transport.tcp.port: 9300-9400  
discovery.zen.ping.multicast.enabled: false  
discovery.zen.ping.unicast.hosts: ["127.0.0.3","192.168.0.1:9300"]  
index.number\_of\_shards: 2  
index.number\_of\_replicas: 1

Let's keep it in [2 nodes with the same cluster but in configured in different machines](https://discuss.elastic.co/t/2-nodes-with-the-same-cluster-but-in-configured-in-different-machines/42004/8)

Hi,

Even am facing similar issue, I have tried setting up cluster using 2 nodes each one on different machines and also I tried 2 nodes on single machine.

In both the cases the nodes are failed to connect to master nodes irrespective of specifying master node and discovery plugin.

error message is "no known master from non-maser nodes" and when connected on browser getting "Cluster block exception".

is there a proper documentation to configure cluster on 2.1.1, can any one help me on this please.

Thanks,  
Chala
