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));
