I am trying to setup a ES 2.3.5 cluster using two nodes. However Node1 and Node2 not joining the cluster , my cluster configuration follows here

Node 1:

[cluster.name](http://cluster.name): mc\_es\_dev  
[node.name](http://node.name): ${HOSTNAME}  
path.data: /opt/es/data  
path.logs: /opt/es/logs  
path.work: /opt/es/work  
bootstrap.mlockall: true  
network.host: "[002.enterprisenet.org](http://002.enterprisenet.org)"  
discovery.zen.ping.unicast.hosts: ["[001.enterprise.org](http://001.enterprise.org)","[002.enterprise.org](http://002.enterprise.org)"]  
http.jsonp.enable: true  
marvel.agent.enabled: false

Node 2:

[cluster.name](http://cluster.name): mc\_es\_dev  
[node.name](http://node.name): ${HOSTNAME}  
path.data: /opt/es/data  
path.logs: /opt/es/logs  
path.work: /opt/es/work  
bootstrap.mlockall: true  
network.host: "[001.enterprisenet.org](http://001.enterprisenet.org)"  
discovery.zen.ping.unicast.hosts: ["[001.enterprise.org](http://001.enterprise.org)","[002.enterprise.org](http://002.enterprise.org)"]  
http.jsonp.enable: true  
marvel.agent.enabled: false

above configuration throws below error while launching ES instance on node1.

Exception in thread "main" BindTransportException[Failed to bind to [9300-9400]]; nested: ChannelException[Failed to bind to: [002.enterprise.org/10.7.xxx.107:9400](http://002.enterprise.org/10.7.xxx.107:9400)]; nested: BindException[Cannot assign requested address];

Refer to the log for complete error details.

Before setting "network.host" property on each Node , each node up and running fine independently but not as a cluster.

Not sure what I am missing here ,any help please?

Thanks

Does that resolve correctly if you ping it?

Thanks Warkolm!

I have found issue in linux server setup itself , had wrong IP placed in /etc/hosts file. Now my cluster ist up and running with two nodes.

Thanks,
