面对过去，不要迷离；面对未来，不必彷徨；活在今天，你只要把自己完全展示给别人看。这个错误是因为客户端试图连接ResourceManager失败，但ResourceManager的地址是0.0.0.0/0.0.0.0:8030。这通常表明网络有问题或 ResourceManager 不在线。
要解决这个问题，请确保 ResourceManager 在线并且可以通过正确的主机名或IP地址访问它。您还可以检查客户端和 ResourceManager 是否在同一个子网内，并且网络配置正确。
如果您在YARN集群上部署了Kubernetes插件，请确保 ResourceManager 的配置正确，并且 ResourceManager 服务器是可见的。例如，您可以使用 kubectl get pods 来检查 ResourceManager pod 的状态，确认其处于运行状态。2023-11-29 14:01:55赞同 展开评论 打赏 -
