I can't get the Java API transport client to work with 5.4.1.
Below is the code snippet:
> ```
> Settings settings = Settings.builder()
> .put("client.transport.sniff", true)
> .put("xpack.security.user", "transport_client_user:changeme")
> .build();
>
> ```
> ```
> client = new PreBuiltXPackTransportClient(settings);
> client = client.addTransportAddresses(new InetSocketTransportAddress(InetAddress.getByName(host), port));
>
> ```
Then I get the following error:
> [elasticsearch[_client_][transport\_client\_boss][T#1]] INFO org.elasticsearch.client.transport.TransportClientNodesService - failed to get local cluster state for {#transport#-1}{uJ\_F0oqAT0ucSdpkfkzpCg}{localhost}{127.0.0.1:9300}, disconnecting...

Reading other problems like this, it seemed this was fixed in 5.4.1. I think it isn't. Will I have to take out the X-Pack plug in?

Did you define a transport\_client\_user user?

Thank you for your reply.
I thought I did, but I fat fingered the user name.
Thanks.
