Let me explain the configuration.

I have setup cluster, name is elasticSearch, of 2 nodes in our data center  
where i forward the logs into these 2 nodes.

I have written a small java client program to access this cluster and is as  
follows:

```
    TransportClient transportClient = new 

```

TransportClient(ImmutableSettings  
.settingsBuilder().put("cluster.name",  
"elasticsearch").build());  
Client client = transportClient.addTransportAddress(  
new InetSocketTransportAddress(InetAddress.getByAddress(new  
byte[] { ), 9300))  
.addTransportAddress(  
new  
InetSocketTransportAddress(InetAddress.getByAddress(new byte[]  
{}), 9300));  
ClusterState clusterState =  
client.admin().cluster().prepareState().execute().actionGet().getState();

node-1-ip,node-2-ip are the nodes address.

To access these machines i have to be VPN. Once I VPN and ran my program  
from my laptop it works. However, when i change the code to

```
    NodeBuilder nb = new NodeBuilder().clusterName("elasticsearch");
    nb.settings().put("node.data", false);
    Node node = nb.client(true).node();
    node.start();

    Client client = node.client();
    ClusterState clusterState = 

```

client.admin().cluster().prepareState().execute().actionGet().getState();

I get the following exception:

Exception in thread "main"  
org.elasticsearch.discovery.MasterNotDiscoveredException: waited for [30s]  
at  
org.elasticsearch.action.support.master.TransportMasterNodeOperationAction$3.onTimeout(TransportMasterNodeOperationAction.java:169)

at  
java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908)  
at java.lang.Thread.run(Thread.java:680)

What am I doing wrong? Why TransportClient is working fine however, when i  
create in memory node client it does not ?

thanks

Probably your cluster does not accept multicast. Firewall???  
You can also use unicast with nodes.

If it is a firewall issue how come TransportClient able to talk to cluster?

Also David, You mentioned about unicast with nodes, how do I do that?

I meant firewall issue for multicast: [Multicast - Wikipedia](http://en.wikipedia.org/wiki/Multicast)  
It's using UDP with:  
group The group address to use. Defaults to 224.2.2.4.  
port The port to use. Defaults to 54328.  
See [Elasticsearch Platform — Find real-time answers at scale | Elastic](http://www.elasticsearch.org/guide/reference/modules/discovery/zen/)

So even if Unicast is working, discovery could not work.

My 2 cents.

Forget to answer to last question.  
See elasticsearch.yml file:  
[https://github.com/elasticsearch/elasticsearch/blob/master/config/elasticsearch.yml#L319](https://github.com/elasticsearch/elasticsearch/blob/master/config/elasticsearch.yml#L319)  
[https://github.com/elasticsearch/elasticsearch/blob/master/config/elasticsearch.yml#L324](https://github.com/elasticsearch/elasticsearch/blob/master/config/elasticsearch.yml#L324)

So set:  
discovery.zen.ping.multicast.enabled: false  
discovery.zen.ping.unicast.hosts: ["node-1-ip:9300", "node-2-ip:9300"]
