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

                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

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

possible problem:

  1. wrong port, if you use a Java or Scala client, correct port is 9300, not 9200
  2. wrong cluster name, make sure the cluster name you set in your code is the same as the cluster.name you set in $ES_HOME/config/elasticsearch.yml
  3. the sniff option, set client.transport.sniff to be true but can't connect to all nodes of ES cluster will cause this problem too. ES doc here explained why.

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));
