解决：如果你配置了es集群的cluster.name，则需要在settings中添加cluster.name的名字，如果没有修改端口号，则客户端的端口号为9300。

Map map = new HashMap();
map.put("cluster.name", "es_test");
Settings.Builder settings = Settings.builder().put(map);
Client client = TransportClient.builder().settings(settings).build()
                .addTransportAddress(new InetSocketTransportAddress(
                        InetAddress.getByName("localhost"), Integer.parseInt("9300")));

再次运行问题解决。
