After connecting to the elasticsearch cluster through the Java API

I'm not able to create a new mapping in the cluster because I get this error on the last line of this piece of code:
```
CreateIndexRequestBuilder createIndexRequestBuilder = client.admin().indices().prepareCreate(indexName);
createIndexRequestBuilder.addMapping(documentName, json);
createIndexRequestBuilder.execute().actionGet();
```

Is the same code that I used with previous versions of the Java API but I didn't get any errors then. I get the ES client with this code:
```
private static Client getClient() {
Settings settings = Settings.settingsBuilder().build();
Client client = null;
TransportClient transportClient = TransportClient.builder().settings(settings).build();
try {
client = transportClient.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName(Receptor.es_ip), 9300));
} catch (UnknownHostException e) {
System.err.println(Util.getTimestampStr() + "UnknownHostException error.");
e.printStackTrace();
}
if(transportClient.connectedNodes() == null){
System.err.println(Util.getTimestampStr() + "No connected nodes found.");
}else{
for(DiscoveryNode d : transportClient.connectedNodes()){
System.err.println(Util.getTimestampStr() + "DiscoveryNode: " + d.getHostName());
}
for(DiscoveryNode d : transportClient.listedNodes()){
System.err.println(Util.getTimestampStr() + "Node: " + d.getHostName());
}
}
return transportClient;
}
```

You use empty settings for TransportClient, but you should declare at least the `cluster.name` you want to connect to, if your cluster name is not `elasticsearch`.

It doesn't matter, I get the same error, I added the cluster line to the getClient() method and I get the error anyway.
```
...
Settings settings = Settings.settingsBuilder().put("cluster.name", Receptor.clusterName).build();
Client client = null;
TransportClient transportClient = TransportClient.builder().settings(settings).build();
...
```

I keep getting the same error. This happen to me since I use elasticsearch 2 and the correspondent Java API for ES 2.

Hi,
I am trying for Nutch 2.3 + ES 2.0 integration. I am not able to index the data fetched from the nutch. I am also facing the same exception.
java.lang.Exception: org.elasticsearch.client.transport.NoNodeAvailableException: None of the configured nodes are available: []
My nutch-site.xml conf :
storage.data.store.class org.apache.gora.mongodb.store.MongoStore Default class for storing data http.agent.name Crawler plugin.includes protocol-(http|httpclient)|urlfilter-regex|index-(basic|more)|query-(basic|site|url|lang)|indexer-elastic|nutch-extensionpoints|parse-(text|html|msexcel|msword|mspowerpoint|pdf)|summary-basic|scoring-opic|urlnormalizer-(pass|regex|basic)|parse-(html|tika|metatags)|index-(basic|anchor|more|metadata) elastic.host 192.168.2.a elastic.cluster uips\_cluster elastic.index nutch parser.character.encoding.default utf-8 http.content.limit 6553600
I have set up ES 2.0 cluster as 1 master 2 nodes with master at 192.168.2.a
Can anyone help me how to resolve this ?
thanks

This problem is a really big one and I would expect more attention to it 😕
My Java program was working perfectly with previous versions of ES.

I found the solution [when I asked in Stackoverflow](http://stackoverflow.com/q/33691858/1051765):
The solution was as straightforward as:
`network.bind_host: 0`
[I found it here](http://stackoverflow.com/questions/33412549/how-to-bind-elasticsearch-2-0-on-both-loopback-and-non-loopback-interfaces/33438638#33438638). It's a problem with the interface in which elasticsearch is bound
