Dear team,  
recently, I using the java API connect the ES 2.3.3 client which has installed the shield. the error as flows:

```
     Exception in thread "main" NoNodeAvailableException[None of the configured nodes are available:

```

BTW, I cannot found the user and password setting in elasticsearch.yml. here was my java code:

public static Client getEsConnection()  
{  
String clusterName = "elasticsearch";

```
    Settings settings = Settings.settingsBuilder()
            .put("cluster.name", clusterName)
            .build();
    Client client = null;
    try {
        client = TransportClient.builder().settings(settings).build()
                .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("10.xx.xx.xx"), 9300))
                .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("10.xx.xx.xx"), 9300))
                .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("10.xx.xx.xx"), 9300));

    } catch (UnknownHostException e) {
        e.printStackTrace();
    }

    return client;

}

```

Levi,  
thanks
