Hi all, My ES cluster has 3 nodes include 10.40.12.51, 10.40.12.52, 10.40.12.53 by TCP transport.  
if I only connect to node 10.40.12.51 (no connect 10.40.12.52, 10.40.12.53 ) the sample code

> ```
> Settings settings = Settings.builder()
> .put("cluster.name","ES_cluster")
> .put("client.transport.ignore_cluster_name",true)
> .put("client.transport.sniff", true)
> .build();
> TransportClient client = new PreBuiltTransportClient(settings);
> client.addTransportAddr
> ess(new InetSocketTransportAddress(InetAddress.getByName(10.40.12.51),"9300"));
> }
> 
> ```

When nodes 10.40.12.51 shutdown, Do TransportClient client auto move connects to node 10.40.12.52 or 10.40.12.53 ?  
Thanks all

Please could you try and format your post a bit better, using the `</>` button for code. It's quite hard to read when it looks like the post above, and this makes it much less likely to receive an answer.

I do not completely understand the question, but I think you are asking how to tell the client to connect to multiple transport addresses. If so, I think the answer is to call `addTransportAddress` multiple times.

(Also, sorry to nitpick, but the greeting "Hi guys" doesn't greet those of us that aren't guys; I suggest saying something like "Hi all" if you want, although no such greeting is really necessary here).
