I am running Elasticsearch 2.1.0 on localhost:9200. What I need to do is read from an index using Java for ES, without having to create a node, because I care about the speed of my application. The following is my code: ``` try (Client client = TransportClient.builder().build() .addTransportAddress(new InetSocketTransportAddress(InetAddress.getLocalHost(), 9200)) .addTransportAddress(new InetSocketTransportAddress(InetAddress.getLocalHost(), 9200))) { QueryBuilder qb = matchQuery( ... ); CountResponse response; response = client.prepareCount(indexName) .setTypes(spammerType).setQuery(qb) .execute() .actionGet(); } ``` However, I am getting the following error: ``` Exception in thread "main" NoNodeAvailableException[None of the configured nodes are available: [{#transport#-1}{127.0.0.1}{localhost/127.0.0.1:9200}]] ``` But I'm trying to avoid creating a node because as I mentioned before, I need my application to be as fast as possible in reading from the index. According to ES: > There are uses-cases for both clients: > > The transport client is ideal if you want to decouple your application > from the cluster. For example, if your application quickly creates and > destroys connections to the cluster, a transport client is much > "lighter" than a node client, since it is not part of a cluster. > > Similarly, if you need to create thousands of connections, you don’t > want to have thousands of node clients join the cluster.

But it ties your > application into the cluster, so it may pose problems from a firewall > perspective. How can I fix the error?? Thanks. ---

Use port 9300 instead. ---

Can I perform a search query using the transport client? Because when I tried port 9300 without the search query, it finally returned no errors (thank you). However, when I added my search query and wanted the result to be returned, I got the `NoNodeException`error again. ---

Of course you can. Look at the Java guide: [https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/java-search.html](https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/java-search.html) ---

Okay, but the following is my search and yet I am receiving the NoNode error: ``` try (Client client = TransportClient.builder().build() .addTransportAddress(new InetSocketTransportAddress(InetAddress.getLocalHost(), 9300)) .addTransportAddress(new InetSocketTransportAddress(InetAddress.getLocalHost(), 9300))) { QueryBuilder qb = matchQuery( "user_name", Username ); CountResponse response = client.prepareCount(indexName) .setTypes(spammerType).setQuery(qb) .execute() .actionGet(); return response; } ``` And the following is the error I am receiving. `Exception in thread "main" NoNodeAvailableException[None of the configured nodes are available: [{#transport#-1}{ **.**. **.** }{ ***/**. **.**.**:9300}]]` When I tried the same query for the node client, it worked for me with no errors. Why is it now showing me that error? Thanks. ---

Hard to say. First guess: cluster name? Second guess: network.host not properly set in your node? ---

I've removed the comment of the [cluster.name](http://cluster.name) in my elasticsearch.yml configuration file and set it to "elasticsearch". Then, I added the following to my application: ``` Settings.Builder st = Settings.builder() .put("cluster.name", "elasticsearch"); try (Client client = TransportClient.builder().settings(st).build() .addTransportAddress(new InetSocketTransportAddress(InetAddress.getLocalHost(), 9300))) ``` But I am still receiving the same error. How can I fix the network.host if it was indeed the problem?? I'm running ES on localhost:9200 and the configurations of that in the elasticsearch.yml are all commented out. ---

This? [https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-network.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-network.html) Define it to your ip address for example. ---

You use `InetAddress.getLocalHost()`, this may return an IPv6 address. Is Elasticsearch configured for IPv6? In the message `Exception in thread "main" NoNodeAvailableException[None of the configured nodes are available: [{#transport#-1}{ **.**. **.** }{ ***/**. **.**.**:9300}]]` you can see the correct IP and Elasticsearch must be configured to this IP. ---

OKay, I got it to work. I defined the network.host in the ES configs to localhost and only then it worked. thanks. ---
