How to connect to AWS Elasticsearch?

Question

I'm trying to connect to AWS Elasticsearch but I always get the following error:

Exception in thread "main" org.elasticsearch.client.transport.NoNodeAvailableException: None of the configured nodes are available: []
at org.elasticsearch.client.transport.TransportClientNodesService.ensureNodesAreAvailable(TransportClientNodesService.java:278)
at org.elasticsearch.client.transport.TransportClientNodesService.execute(TransportClientNodesService.java:197)
at org.elasticsearch.client.transport.support.InternalTransportClient.execute(InternalTransportClient.java:106)
at org.elasticsearch.client.support.AbstractClient.index(AbstractClient.java:98)
at org.elasticsearch.client.transport.TransportClient.index(TransportClient.java:334)

at com.c_backendcrawler.utility.ElasticSearch.uploadObject(ElasticSearch.java:25)
at com.c_backendcrawler.Start.main(Start.java:34)

My code is following:

 //Create Client
    Settings settings = ImmutableSettings.settingsBuilder().put("cluster.name", "zencubes-search").put("node.name","Darkhawk").build();
    TransportClient transportClient = new TransportClient(settings);
    transportClient.addTransportAddress(new InetSocketTransportAddress(
            "x.x.x.x",9300));
    return transportClient;

Output from AWS Elasticsearch:

    {
status: 200,
name: "Darkhawk",
cluster_name: "817880037706:zencubes-search",
version: {
number: "1.5.2",
build_hash: "62ff9868b4c8a0c45860bebb259e21980778ab1c",
build_timestamp: "2015-04-27T09:21:06Z",
build_snapshot: false,
lucene_version: "4.10.4"
},
tagline: "You Know, for Search"
}

I tried to curl (https://search-zencubes-search-xxxxxxxx.eu-west-1.es.amazonaws.com/ ) and it works - but not on port 9300. What am I doing wrong here?

The native transport protocol is not support using AWS Managed ElasticSearch and is only available over the REST endpoint. Consider switching your client to consume the REST endpoint, such as https://github.com/searchbox-io/Jest.
