I'm trying to make my first Java application to talk to ElasticSearch, which is running on this node (timestamps removed): ``` $ bin/elasticsearch [2015...][WARN][bootstrap] Unable to lock JVM Memory: error=78,reason=Function not implemented [2015...][WARN][bootstrap] This can result in part of the JVM being swapped out.

I'm [reasonably sure](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-transport.html) that port 9300 is correct for a Java TransportClient. But this ``` public class TrivialClient { public static void main(String[] args) throws UnknownHostException { Client client = TransportClient.builder().build(). addTransportAddress(new InetSocketTransportAddress( InetAddress.getLocalHost(), 9300)); printResponse("getLocalHost", client); client = TransportClient.builder().build(). addTransportAddress(new InetSocketTransportAddress( InetAddress.getByName("localhost"), 9300)); printResponse("getByName(\"localhost\")", client); client = TransportClient.builder().build(). addTransportAddress(new InetSocketTransportAddress( InetAddress.getByAddress(new byte[] {127, 0, 0, 1}), 9300)); printResponse("getByAddress(new byte[] {127, 0, 0, 1})", client); } private static void printResponse(String description, Client client) { try { GetResponse response = client.prepareGet("comicbook", "superhero", "1").get(); System.out.println(description + ": " + response); } catch (NoNodeAvailableException e) { System.out.println(description + ": " + e); } } } ``` Outputs this ``` getLocalHost: NoNodeAvailableException[None of the configured nodes are available: []] getByName("localhost"): NoNodeAvailableException[None of the configured nodes are available: []] getByAddress(new byte[] {127, 0, 0, 1}): NoNodeAvailableException[None of the configured nodes are available: []] ``` This ``` client = TransportClient.builder().build(). addTransportAddress(new InetSocketTransportAddress("localhost", 9200)); ``` which is valid according to [this question](http://stackoverflow.com/questions/16670219/why-cant-i-connect-to-elasticsearch-through-java-api), does not even compile. My clustername is different, so I've also tried it with this at the top ``` Settings settings = Settings.settingsBuilder() .put("cluster.name", "clustername").build(); ``` (and added `settings(settings)` to each builder), but same error. What am I missing? ---

I think your clustername is `myusername-elasticsearch-local`, right? This is incorrect: ```auto client = TransportClient.builder().build(). addTransportAddress(new InetSocketTransportAddress("localhost", 9200)); ``` Should be `9300` and the code does not compile with 2.0. You should write something like: ```auto Settings settings = Settings.settingsBuilder() .put("cluster.name", clusterName).build(); Client client = TransportClient.builder().settings(settings).build() .addTransportAddress(new InetSocketTransportAddress(new InetSocketAddress("127.0.0.1", 9300))); ``` Actually this code is working for me. ---

I was wondering if it was a version issue. Perhaps there's a version 2 of the book-tutorial that I've missed. Unfortunately, that also gives me the same error 😞 I need to figure this out, and I'm unsure how to further diagnose it. I'm experienced with server side Java, but am new to ElasticSearch. Thank you for your time, dadoonet. ---

New code, which does exactly the same thing, but separates out the problem stuff better: ``` import org.elasticsearch.action.get.GetResponse; import org.elasticsearch.client.Client; import org.elasticsearch.client.transport.NoNodeAvailableException; import org.elasticsearch.client.transport.TransportClient; import org.elasticsearch.common.settings.Settings; import org.elasticsearch.common.transport.InetSocketTransportAddress; import java.net.InetAddress; import java.net.InetSocketAddress; import java.net.UnknownHostException; public class TrivialClient { public static void main(String[] args) throws UnknownHostException { InetSocketTransportAddress transportAddress = new InetSocketTransportAddress( InetAddress.getLocalHost(), 9300); createClientPrintResponse("getLocalHost", transportAddress); transportAddress = new InetSocketTransportAddress( InetAddress.getByName("localhost"), 9300); createClientPrintResponse("getByName(\"localhost\")", transportAddress); //Does not compile in ElasticSearch 2.0 // transportAddress = new InetSocketTransportAddress("localhost", 9200); // createClientPrintResponse("getByName(\"localhost\")", transportAddress); transportAddress = new InetSocketTransportAddress( InetAddress.getByAddress(new byte[]{127, 0, 0, 1}), 9300); createClientPrintResponse("getByAddress(new byte[] {127, 0, 0, 1})", transportAddress); transportAddress = new InetSocketTransportAddress(new InetSocketAddress("127.0.0.1", 9300)); createClientPrintResponse("InetSocketAddress", transportAddress); } private static void createClientPrintResponse(String description, InetSocketTransportAddress transportAddress) { Settings settings = Settings.settingsBuilder() .put("cluster.name", "epsteinj-elasticsearch-local").build(); Client client; client = TransportClient.builder().settings(settings).build(). addTransportAddress(transportAddress); try { GetResponse response = client.prepareGet("comicbook", "superhero", "1").get(); System.out.println(description + ": " + response); } catch (NoNodeAvailableException e) { System.out.println(description + ": " + e); //e.printStackTrace(); } } } ``` Output without stack traces: ``` getLocalHost: NoNodeAvailableException[None of the configured nodes are available: []] getByName("localhost"): NoNodeAvailableException[None of the configured nodes are available: []] getByAddress(new byte[] {127, 0, 0, 1}): NoNodeAvailableException[None of the configured nodes are available: []] InetSocketAddress: NoNodeAvailableException[None of the configured nodes are available: []] ``` Stack trace: ``` NoNodeAvailableException[None of the configured nodes are available: []] getLocalHost: NoNodeAvailableException[None of the configured nodes are available: []] at org.elasticsearch.client.transport.TransportClientNodesService.ensureNodesAreAvailable(TransportClientNodesService.java:280) at org.elasticsearch.client.transport.TransportClientNodesService.execute(TransportClientNodesService.java:197) at org.elasticsearch.client.transport.support.TransportProxyClient.execute(TransportProxyClient.java:55) at org.elasticsearch.client.transport.TransportClient.doExecute(TransportClient.java:272) at org.elasticsearch.client.support.AbstractClient.execute(AbstractClient.java:347) at org.elasticsearch.action.ActionRequestBuilder.execute(ActionRequestBuilder.java:85) at org.elasticsearch.action.ActionRequestBuilder.execute(ActionRequestBuilder.java:59) at org.elasticsearch.action.ActionRequestBuilder.get(ActionRequestBuilder.java:67) at springes.esonly.TrivialClient.createClientPrintResponse(TrivialClient.java:47) at springes.esonly.TrivialClient.main(TrivialClient.java:19) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:497) at com.intellij.rt.execution.application.AppMain.main(AppMain.java:144) ``` ---

Did you manage to solve this. I have read its an issue with the version? ---

I downloaded version 1.7.1 and the same code worked no problem. ---
