your initialization of es transport client is wrong:

Here is an simple example of initialization:

Settings settings = Settings.builder()
    .put("cluster.name", "myClusterName").build();
TransportClient client = new PreBuiltTransportClient(settings).addTransportAddress(new TransportAddress(InetAddress.getByName("host1"), 9300))
    .addTransportAddress(new TransportAddress(InetAddress.getByName("host2"), 9300));
