我有一个运行在minikube中的spark集群：

$ k get pods                                                                                                                                              
NAME             READY   STATUS    RESTARTS   AGE
spark-master-0   1/1     Running   0          7d
spark-worker-0   1/1     Running   0          7d
spark-worker-1   1/1     Running   0          7d

我已将端口转发给master：

$ k port-forward spark-master-0 8080:8080                                                                                                                   
Forwarding from 127.0.0.1:8080 -> 8080
Forwarding from [::1]:8080 -> 8080

我正在尝试创建一个JavaSparkSession，但我不确定要使用哪个主URL：

SparkConf sparkConf = new SparkConf()
    .setMaster("???")
    .setAppName("test-spark");
SparkSession.builder()
    .config(sparkConf)
    .getOrCreate();

已尝试以下方法，但未成功

• "local"
• "localhost:8080
• http://localhost:8080
• spark://localhost:8080
• （来自其中一个答案）k8s://http://192.168.1.2:8080
• （来自其中一个答案）k8s://https://kubernetes:443

它们都不起作用。得到以下错误：

Caused by: org.apache.spark.SparkException: Could not parse Master URL: '<MASTER URL FROM LIST ABOVE>'

我用什么主URL？谢谢

EDITUrl spark://192.168.58.2:7077部分工作，出现如下错误：
