It's an elasticsearch Transport client. You need to initialize it like below:

import org.elasticsearch.client.transport.TransportClient;
import org.elasticsearch.common.settings.Settings;
import org.elasticsearch.common.transport.InetSocketTransportAddress;

Settings settings = Settings.builder()
.put("cluster.name", "my_cluster").build();
TransportClient client = new PreBuiltTransportClient(settings)
.addTransportAddress(new InetSocketTransportAddress(InetAddress.getLocalHost(),9300));
