Java Question

Java ElasticSearch None of the configured nodes are available

Just downloaded and installed elasticsearch 1.3.2 in past hour

Opened IP tables to port 9200 and 9300:9400

Set my computer name and ip in /etc/hosts

Head Module and Paramedic Installed and running smoothly

curl on localhost works flawlessy

copied all jars from download into eclipse so same version client

--Java--

import org.elasticsearch.action.search.SearchResponse;
import org.elasticsearch.client.Client;
import org.elasticsearch.client.transport.TransportClient;
import org.elasticsearch.common.settings.ImmutableSettings;
import org.elasticsearch.common.settings.Settings;
import org.elasticsearch.common.transport.InetSocketTransportAddress;
import org.elasticsearch.index.query.QueryBuilders;


public class Test{
public static void main(String[] args) {
Settings settings = ImmutableSettings.settingsBuilder().put("cluster.name", "elastictest").build();
TransportClient transportClient = new TransportClient(settings);
Client client = transportClient.addTransportAddress(new InetSocketTransportAddress("143.79.236.xxx",9300));//just masking ip with xxx for SO Question

try{
SearchResponse response = client.prepareSearch().setQuery(QueryBuilders.matchQuery("url", "twitter")).setSize(5).execute().actionGet();//bunch of urls indexed
String output = response.toString();
System.out.println(output);
}catch(Exception e){
e.printStackTrace();
}
client.close();
}
}


--Output--

Update: Now I am REALLY confused. I just pressed run in eclipse 3 times. 2 times received the error above. 1 time the search worked!?? Brand new Centos 6.5 vps, brand new jdk installed. Then installed elasticsearch, have done nothing else to box.

Update: After running ./bin/elasticsearch console

--cluster config in elasticsearch.yml--

################################### Cluster ###################################

# Cluster name identifies your cluster for auto-discovery. If you're running
# multiple clusters on the same network, make sure you're using unique names.
#
cluster.name: elastictest

Answer

Elasticsearch settings are in $ES_HOME/config/elasticsearch.yml. There, if the cluster.name setting is commented out, it means ES would take just about any cluster name. So, in your code, the cluster.name as "elastictest" might be the problem. Try this:

Client client = new TransportClient()
                .addTransportAddress(new InetSocketTransportAddress(
                        "143.79.236.xxx",
                        9300));
