7.org.elasticsearch.transport.RemoteTransportException: Failed to deserialize exception response from stream
原因:es节点之间的JDK版本不一样
解决方法：统一JDK环境
1） 端口错
client = new TransportClient().addTransportAddress(new InetSocketTransportAddress(ipAddress, 9300));
这里9300 写成9200的话会No node available
要是你连的不是本机，注意IP有没有正确
2 ）jar报引用版本不匹配，开启的服务是什么版本，引用的jar最好匹配（这个我没有去试，反正我的是匹配的）
3） 要是你改了集群名字，还有设置集群名字
Settings settings = ImmutableSettings.settingsBuilder().put("cluster.name", "xxx").build();
client = new TransportClient(settings).addTransportAddress(new InetSocketTransportAddress(ipAddress, 9300));

es服务器版本和java客户端中版本不一致：
