我能够在 k8s 中执行 SparkPi 并部署（在 GKE 中）。

但是，当我尝试将 PI 值广播到我的微服务时toys-broadcast-svc.toys.svc.cluster.local

我无法解析 DNS（获取UnknownHostException）。任何人都可以帮忙吗？我在这里错过了什么吗？

供您参考：

  • 我已经用 helm 安装了操作员 helm install sparkoperator incubator/sparkoperator --namespace toys-spark-operator --set sparkJobNamespace=toys-spark,enableWebhook=true

  • 我正在使用 spark-operator（微服务在命名空间中toys ，火花在命名空间中toys-spark）
