NoNodeAvailableException[None of the configured nodes are available exception

Elastic Stack Elasticsearch
1

I am using ES 5.4.2 and Java 1.8 and getting below error while connecting to local ES server.

Exception in thread "main" NoNodeAvailableException[None of the configured nodes are available: [{#transport#-1}{cv2EOOhCQ3OeqIFvyfrtYQ}{127.0.0.1}{127.0.0.1:9300}]]

Code:

     Settings settings = Settings.builder()
        .put("client.transport.nodes_sampler_interval", "5s")
        .put("client.transport.sniff", false)
        .put("transport.tcp.compress", true)
        .put("cluster.name", clusterName)
        .put("request.headers.X-Found-Cluster", "${cluster.name}")
        .build();

 TransportClient client = new PreBuiltTransportClient(settings);
 client.addTransportAddress(new InetSocketTransportAddress(address, port));
ActionFuture<ClusterHealthResponse> healthFuture = 
client.admin().cluster().health(Requests.clusterHealthRequest());
            ClusterHealthResponse healthResponse = healthFuture.get(5, TimeUnit.SECONDS);

I think you should read this: https://www.elastic.co/guide/en/x-pack/current/java-clients.html

3

But im using it in local..do i still need to code the Xpack way ?

I was confused by:

        .put("request.headers.X-Found-Cluster", "${cluster.name}")

Which means to me that you are trying to connect to a cloud cluster.

If local, then it looks good but I'd remove all the Settings but cluster.name.

yml file content : xpack.security.enabled: false

Java Code:

     Settings settings =Settings.builder()
	    		.put("client.transport.sniff",true)
	    		.put("cluster.name", "my-application").build();

       TransportClient  client = new PreBuiltTransportClient(settings)
        .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("127.0.0.1"), 9300));

       CreateIndexRequestBuilder createIndexRequestBuilder = client.admin().indices().prepareCreate("subu");
       createIndexRequestBuilder.execute().actionGet();
6

Can you remove .put("client.transport.sniff",true)?

7

tried that also still not working

8

Can you share your full elasticsearch logs?

Nothing looks very bad.

I mean that I'm not expecting such a None of the configured nodes are available.

That said:

client.admin().indices().prepareCreate("subu").get();

Might be problematic on your cluster because you are running low on disk space:
