Spring Elasticsearch - None of the configured nodes are available

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 youhaven'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.

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)));
