Issue with TransportClient on 5.2.1

i'm assuming PreBuiltTransportClient is a class i create that should derive from TransportClient?our old code(2.3.1) is as follows:

Nope. PreBuiltTransportClient is provided in elasticsearch jar.

In your settings, I'd just keep:

settings.put("client.transport.sniff", config.getBoolean("client.transport.sniff", true));
settings.put("client.transport.ping_timeout", config.get("client.transport.ping_timeout", "10s"));
settings.put("client.transport.nodes_sampler_interval", config.get("client.transport.nodes_sampler_interval", "10s"));

And please format your code using </> icon as explained in this guide. It will make your post more readable.

Or use markdown style like:
