I'm working on some simple tests with Spark (standalone mode) and ElasticSearch. All my tests work fine as long as ElasticSearch is running in the same host as Spark. If I move ElasticSearch to a different node, then I get an exception "org.elasticsearch.hadoop.rest.EsHadoopTransportException: java.net.NoRouteToHostException: ..."

I have discarded any network / firewall issues, since I'm able to connect using kibana to the remote ElasticSearch node.

The test is as simple as this:

```auto
val spark = SparkSession.builder.master("local").appName("testing")
   .config("es.nodes", "remotenode")
   .getOrCreate()

spark.sparkContext.esRDD("radio/artists")
Console.out.println(RDD.count())

```

I'm using Spark 2.11 with elasticSearch-spark-20\_2.11-5.3.2.

Any help?... I don't know what else to try!

On your remote ES node run the following:

nslookup remotenode

nslookup ON\_IP\_FROM\_ABOVE

what is the output?

nslookup:  
Non-authoritative answer:

Authoritative answers can be found from:

61.58.80.in-addr.arpa nameserver = [rsdbgi1-11.rima-tde.net](http://rsdbgi1-11.rima-tde.net).

I don't have a DNS configured for my test network... Shall I?

Yes, you should configure DNS if you plan to use hostnames as the problem is it can not resolve what is "es.nodes" = "remotenode" . The alternative is you can always use the IP address , e.g. "es.nodes" = "192.68.1.101:9200"
