I keep getting this "unknown setting [xpack.security.user] please check that any required plugins are installed," error. from document, it says

> At a minimum, you must configure xpack.security.user to include the name and password of your transport client user in your requests. The following snippet configures the user credentials globally—every request submitted with this client includes the transport\_client\_user credentials in its headers.

am I missing any library?

instead of using the right client:

client = new PreBuiltXPackTransportClient(settings);

I using this, which cause the error:

TransportClient client = new PreBuiltTransportClient(settings)
