**Hello**

**I created two nodes (elasticsearch-node, client-node) on the same machine. Started them. Configuration is as follows:**

1. 

[cluster.name](http://cluster.name): production  
[node.name](http://node.name): elasticsearch-node  
node.master: true  
node.data : true  
2.  
[cluster.name](http://cluster.name): production  
[node.name](http://node.name): client-node  
node.master: false  
node.data : true

**Both the nodes started.**

**Java code:**

```
	Settings settings = Settings.builder()
	        .put("cluster.name", "production")
	        .put("node.name","elasticsearch-node")
	        .build();
	TransportClient client = new PreBuiltTransportClient(settings);

```

**When I try to connect through Java, I am getting the following exception:**

NoNodeAvailableException[None of the configured nodes are available: []]  
org.elasticsearch.client.transport.TransportClientNodesService.ensureNodesAreAvailable(TransportClientNodesService.java:347)

**Any insights?**

**Thank You**

You did not define the node to connect to.

BTW [node.name](http://node.name) is useless in the context of the transport client.
