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#L324
So set:
discovery.zen.ping.multicast.enabled: false
discovery.zen.ping.unicast.hosts: ["node-1-ip:9300", "node-2-ip:9300"]

I meant firewall issue for multicast: Multicast - Wikipedia
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
So even if Unicast is working, discovery could not work.
My 2 cents.

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?

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

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[] { <node-1-ip>), 9300))
.addTransportAddress(
new InetSocketTransportAddress(InetAddress.getByAddress(new byte[] {<node-2-ip>}), 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)

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