elasticsearch AWS工人可以'；由于Netty客户端主机名解析，无法进行通信
我实际上正在研究拓扑，从卡夫卡那里获取数据，并将它们持久化到elasticsearch中。好的，首先，我使用storm dependency中的基本KafkaSpout来侦听来自精确kafka主题的数据，并且，我重新实现了Elasticsearch hadoop项目中的Elasticsearch bolt:。目标是在elasticsearch中写几个索引。 因此，当我处理来自kafka的消息时，当kafka队列中的数据数量增加时，我会遇到一些异常。这是工作日志中堆栈跟踪的一部分：

非常感谢 我从谷歌来到这里，寻找类似问题的答案。就我而言，错误是：
o.a.s.m.n.Client [ERROR] connection attempt 104 to Netty-Client-ip-XXX-XXX-XXX-XXX.ec2.internal/XXX.XXX.XXX.XXX:6703 failed: java.net.ConnectException: Connection refused: ip-XXX-XXX-XXX-XXX.ec2.internal/XXX.XXX.XXX.XXX:6703

不管怎样，一旦我设置了正确的默认java版本，它就开始生效了。我从谷歌来到这里，寻找类似问题的答案。就我而言，错误是：
