Spring Data ElasticSearch - cannot connect to node

Question

I'm trygin to configure ElasticSearch repositories in Spring MVC application. I'm using Spring Data ElasticSearch version: 2.0.7 and ElasticSearch Server 2.4.4.

I'm sure that ElasticNode work, here is sample output

$ curl -X GET http://127.0.0.1:9200/
{
  "name" : "Tattoo",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "dX0lPfNnSA6vxGqhzVEuSg",
  "version" : {
    "number" : "2.4.4",
    "build_hash" : "fcbb46dfd45562a9cf00c604b30849a6dec6b017",
    "build_timestamp" : "2017-01-03T11:33:16Z",
    "build_snapshot" : false,
    "lucene_version" : "5.5.2"
  },
  "tagline" : "You Know, for Search"
}

Here is my test configuration

@Configuration
@EnableElasticsearchRepositories(basePackages = "com.somepackage.repo.elastic")
public class ElasticSearchConfig {

@Bean
public ElasticsearchTemplate elasticsearchTemplate() throws UnknownHostException {
    return new ElasticsearchTemplate(nodeClient());
}

@Bean
public TransportClient nodeClient() throws UnknownHostException {

    Settings settings = Settings.builder().put("cluster.name", "elasticsearch").build();
    TransportClient client = TransportClient.builder()
            .settings(settings)
            .build();
    client.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"), 9200));
    return client;

}
}

I'm getting errors that application cannot connect to Elastic node, stacktrace

2017-02-17 23:34:53 INFO  transport:383 - [Impulse] failed to get node info for {#transport#-1}{127.0.0.1}{localhost/127.0.0.1:9200}, disconnecting...

I tried to change versions of elastic search nodes from 1.7.1, 2.4.4 and 5.2.1. Nothing works. Spring MVC 4.3.6.RELEASE with Java 8

The Transport client talks to elasticsearch over port 9300. So try

client.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"), 9300));

In short: ElasticSearch node and TransportClient should have the same version.

Spring Data ElasticSearch provides TransportClient in version 2.2.0. I was using ElasticSearch node in version 2.4.4. I downgraded ES node to 2.2.0 and change port from 9200 to 9300 in configuration.

You are correct. Gladly I did not have have problems with version of TransportClient. Still good to know that for future. But I had a lot of issues because I did not understand 9200 and 9300 default ports. Here is discussion when to use which one which helped me: elasticsearch-users.115913.n3.nabble.com/…
