当安定性索引数据发送到德鲁伊时，java.nio.channels.UnresolvedAddressException

Question

我正在尝试使用Druid 0.11和Kafka进行安定。 当宁静收到新数据时，它将引发以下异常：

2018-01-12 18:27:34,010 [Curator-ServiceCache-0] INFO  c.m.c.s.net.finagle.DiscoResolver - Updating instances for service[firehose:druid:overlord:flow-018-0000-0000] to Set(ServiceInstance{name='firehose:druid:overlord:flow-018-0000-0000', id='ea85b248-0c53-4ec1-94a6-517525f72e31', address='druid-md-deployment-7877777bf7-tmmvh.druid-md-hs.default.svc.cluster.local', port=8100, sslPort=-1, payload=null, registrationTimeUTC=1515781653895, serviceType=DYNAMIC, uriSpec=null})

该工作人员是由中层经理创建的：

和安宁与霸王交谈...我认为以下日志：

怎么了？ 我尝试了上千种方法，但没有解决方法...

非常感谢

Druid经纪人击中UnresolvedAddressException

您必须在运行稳定的服务器中设置所有druid群集信息。 这是因为您只从Zookeeper获得了德鲁伊集群的DNS，而不是IP。 例如，在linux服务器上，将群集信息保存在/ etc / hosts中。
