        public void before() {
            try {
                 client = new PreBuiltTransportClient(
                        Settings.builder().put("cluster.name", "elasticsearch").put("client.transport.sniff", true)
                        .build())
                         .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"), 9300));
            } catch (UnknownHostException e) {

            IndexResponse response = client.prepareIndex("twitter", "tweet")
                    .setSource(json, XContentType.JSON)
