elastic4s org.elasticsearch.client.transport.NoNodeAvailableException:

Question

I'm having issues connecting to a local version of elasticsearch. I'm doing the following

val uri = ElasticsearchClientUri("elasticsearch://127.0.0.1:9300")
val client = ElasticClient.remote(uri)
lient execute { search in "_all" query "test" }

But get a

org.elasticsearch.client.transport.NoNodeAvailableException: None of the    configured nodes are available: []

exception. It doesn't matter if I go between 9200 / or 9300. ES is up and running correctly as far as I can see. Any pointers appreciated.

Hello Steve, can you check this link: https://github.com/sksamuel/elastic4s See if it helps you. — A Coder Gamer, May 06 '16 at 17:00
how come you are using remote with local address? Can you hit your local instance at 9200 with basic GET request to see it s responding? — Barry, May 06 '16 at 18:01
I was able to connect to my local instance with just ```val client = ElasticClient.local``` — Barry, May 06 '16 at 18:31
What is the versions of client and server? They can be inconpetible. — alpert, May 06 '16 at 20:12
Hi @AkshayBijawe thanks for the comment - I've been basing the examples off of that and a few other derivatives but none worked :-( — Steve, May 06 '16 at 22:41

In your local ElasticSearch instance, have you modified cluster.name in elasticsearch.yml? In that case you need to build Settings object.

val settings = Settings.settingsBuilder().put("cluster.name", "cluster_name").build()    // set cluster_name to cluster.name from your elasticsearch.yml
val uri = ElasticsearchClientUri("elasticsearch://127.0.0.1:9300")
client = ElasticClient.remote(settings, uri)

There are some possible reasons for this:

The client and server versions can be different
Cluster name can be different
There could be a network problem when accesing the host and port.

How to create elasticsearch 2.4.0 transport client using scala?

import com.sksamuel.elastic4s.ElasticDsl._
import com.sksamuel.elastic4s.{ElasticsearchClientUri, ElasticClient}
import org.elasticsearch.common.settings.Settings    
object Facebook {
        def main(args: Array[String]) {


    val settings = Settings.builder().put("cluster.name", "myClusterName").build()
    val client = ElasticClient.transport(settings, ElasticsearchClientUri("elasticsearch://localhost:9300"))
          client.execute { createIndex("places") shards 3 replicas 2 }
        }
    }

scala maven dependencies:

    <dependency>
        <groupId>com.sksamuel.elastic4s</groupId>
        <artifactId>elastic4s-core_2.11</artifactId>
        <version>2.4.0</version>
