I configured two node with the cluster name (production), but when I installed head plugin I didn't see the two nodes. I saw the node which it's address is used to open head plugin

For instance : 9200/\_plugin/head will show me the node1 as master and as the only node in the cluster, the same thing goes for the node2.

My configuration :

==\>node1 :

[cluster.name](http://cluster.name): production  
index.numer\_of\_shards : 5  
index .number\_of\_replicas : 0  
[node.name](http://node.name): node1  
network.host: node1 Ip Add  
discovery.zen.ping.unicast.hosts: [node1 Ip Add ,node2 Ip Add]  
discovery.zen.ping.multicast.enabled: false  
discover.zen.ping.timeout: 20s

==\>node2 :

[cluster.name](http://cluster.name): production  
index.numer\_of\_shards : 5  
index .number\_of\_replicas : 0  
network.host: node2 Ip Add  
[node.name](http://node.name): node2  
discovery.zen.ping.unicast.hosts: [node1 Ip Add ,node2 Ip Add]  
discovery.zen.ping.multicast.enabled: false  
discover.zen.ping.timeout: 20s
