我能够在k8s中执行sparkpi并部署（在gke中）。
但是，当我试图向我的微服务广播pi值时 toys-broadcast-svc.toys.svc.cluster.local 我无法解析dns（未知hostexception）。有人能帮忙吗？我是不是漏了什么？
供参考：
我已经安装了舵机 helm install sparkoperator incubator/sparkoperator --namespace toys-spark-operator --set sparkJobNamespace=toys-spark,enableWebhook=true 我正在使用spark操作符（microservice在名称空间中称为 toys spark在命名空间中称为 toys-spark )
