由日志得知

org.apache.curator.framework.imps.EnsembleTracker.processConfigData(EnsembleTracker.java:214)

是 curator 组件的 EnsembleTracker 的 214 行日志错误

顺藤摸瓜

得知，是日志级别的问题，不是异常

搜索引擎搜一下，看是否有人遇到过类似的问题

https://github.com/apache/druid/issues/11971

https://issues.apache.org/jira/browse/CURATOR-526

https://github.com/apache/curator/pull/382

得知这个问题是日志级别设置错误了，在 curator 5.x 修复了这个问题，自己在试了 maven 仓库中从 5.0.0 开始的版本，从 5.2.0 中开始变成了 info。
