Spring Elasticsearch - None of the configured nodes are available

Question

I am using spring-boot with Elasticsearch. The project was created using jhipster.

pom.xml contains:

<parent>
  <artifactId>spring-boot-starter-parent</artifactId> 
  <groupId>org.springframework.boot</groupId>
  <version>1.4.0.RELEASE</version>
  <relativePath/>
</parent>

and

<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-data-elasticsearch</artifactId>
</dependency>

In production mode, the following error occurs:

AbstractElasticsearchRepository : failed to load elasticsearch nodes :    
org.elasticsearch.client.transport.NoNodeAvailableException: None of  
the configured nodes are available: [{#transport#-1}{127.0.0.1}
{localhost/127.0.0.1:9300}]

How can I resolve this error?

Answer 1

In development profile, JHipster uses an embedded Elasticsearch.

In production profile, it tries by default to connect to a local cluster, so either you don't have installed Elasticsearch on your local machine or you haven't configured the right URL in application-prod.yml to connect to an existing cluster.

First of all thanks Gaël Marziou. I installed Elasticsearch on my local machine but the problem persist. So, this is my application-prod.yml file.

Answer 3

I change my elasticTemplate method in ElasticSearchConfiguration.java and works fine. I just add the follow lines and set my cluster node name to "Gibborim" in Elasticsearch 2.0.

Settings settings = Settings.settingsBuilder()
        .put("client.transport.sniff", true).put("name","Gibborim").put("cluster.name", "elasticsearch").put("network.host","127.0.0.1").build();

    client = TransportClient.builder().settings(settings).build().addTransportAddress(new InetSocketTransportAddress(new InetSocketAddress("127.0.0.1", 9300)));

Answer 4

If you run jhipster project with default elasticsearch configuration then be sure that your elasticsearh server version is 1.7 because jhipster java project works with this version(in production profile)

In development profile there was such a problem which I couldn't solve yet
