线程"main" org.apache.spark.SparkException 中的异常：必须指定驱动程序容器映像

Question

>我正在尝试使用命令从本地机器 CLI 在 minikube(Kubernetes( 上进行 spark-submit

spark-submit --master k8s://https://127.0.0.1:8001 --name cfe2 
--deploy-mode cluster --class com.yyy.Test --conf spark.executor.instances=2 --conf spark.kubernetes.container.image docker.io/anantpukale/spark_app:1.1 local://spark-0.0.1-SNAPSHOT.jar

我有一个简单的火花工作罐子，基于 verison 2.3.0 构建。我还在 docker 和 minikube 中将其容器化，并在虚拟盒子上运行。下面是异常堆栈：

Answer 1

看起来像参数默认值的错误 spark.kubernetes.driver.container.image ，必须spark.kubernetes.container.image 。因此，请尝试直接指定驱动程序/执行程序容器映像：

• spark.kubernetes.driver.container.image
• spark.kubernetes.executor.container.image

Answer 2

从源代码来看，唯一可用的 conf 选项是：

spark.kubernetes.container.image
spark.kubernetes.driver.container.image
spark.kubernetes.executor.container.image

我注意到，与 2.2.0

相比，Spark 2.3.0 在 k8s 实现方面发生了很大变化。例如，官方入门指南不是单独指定驱动程序和执行器，而是使用提供给spark.kubernetes.container.image的单个图像。

看看这是否有效：

spark-submit 
--master k8s://http://127.0.0.1:8001 
--name cfe2 
--deploy-mode cluster 
--class com.oracle.Test 
--conf spark.executor.instances=2 
--conf spark.kubernetes.container.image=docker/anantpukale/spark_app:1.1 
--conf spark.kubernetes.authenticate.submission.oauthToken=YOUR_TOKEN 
--conf spark.kubernetes.authenticate.submission.caCertFile=PATH_TO_YOUR_CERT 
local://spark-0.0.1-SNAPSHOT.jar

令牌和证书可以在 k8s 仪表板上找到。按照说明制作与 Spark 2.3.0 兼容的 docker 映像。
