I setting two ES nodes as client node in my ES cluster, i want the application only connect the client node for query or index. But when set client node's IP for connection, found that my application also connect the master node or data node . how can i force the application only connect the client node ? then client nodes handle the task(query or index) distribution. ---

What are you using to connect to the client nodes? ---

TransportClient to connect the nodes ---

Then that's why. You will need to use just HTTP and only list those two clients. ---

ok! you mean client nodes only used for HTTP connection? TCP connection can not do the work that the question shows ? ---

No, I mean that using either transport or node clients will cause your client to load balance across all nodes in the cluster. ---

which http client you suggest ? [https://github.com/searchbox-io/Jest](https://github.com/searchbox-io/Jest) is stable for production environment ? thanks ---

Using TransportClient is the way to go. As long you don't set `client.transport.sniff` to `true`, the TransportClient will connect only to the nodes you defined in it. I'm surprised you are seeing something else. ---

@dadoonet is right there, that's my mistake sorry! ---

i have set "client.transport.sniff=false" already. but i can see other nodes which are not client node type. when check the ES nodes' connections, i am sure the application servers connect the master node and data node, not only client node. the shell code "netstat -anp | grep "9300" ---

Any chance you can share details about your findings? - Java client code - Output of `_cat/nodes?v` - Output of `netstat -anp | grep "9300"` ---
