ES5.4中Java Transport Client 报错问题

如题,本人从5.1.2跟随每次版本升级java Transport client都没出现这个问题,今天升级到5.4.0后,ES集群没问题,工程配置依赖jar也没问题。
正常的搜索请求都没问题,而且也能正常返回结果,就是日志每隔几秒就出现如下日志,看起来很烦人。
日志如下
[elasticsearch[_client_][generic][T#3]] TransportClientNodesService$SniffNodesSampler$1$1.handleException (TransportClientNodesService.java:531) - failed to get local cluster state for {#transport#-1}{cAagOGR2SoSZJv5HEBB8GA}{172.xx.xx.xx}{172.xx.xx.xx:9300}, disconnecting...

以及单次与集群建立通信的完整日志信息:

其中172.xx.xx.xx是机器ip地址

试了好多种配置方法还是会每隔几秒一次打那个日志,求大神指定。

我把Settings.builder()里自动嗅探节点"client.transport.sniff"改成false虽然没问题了,但是很不科学啊

一共几个节点啊?
172.xx.xx.xx:9308是那台节点啊?
