apache-spark - 启动容器进程导致\“exec:\\\”驱动程序\\\“: executable file not found in $PATH\”\n“

Question

我有基于Spring的spark 2.3.0应用程序。我正在尝试在kubernetes(minikube)上进行 Spark 提交。
我有运行docker和minikube的Virtual Box。opt/spark/bin/spark-submit --master k8s://https://192.168.99.101:8443 --name cfe2 --deploy-mode cluster --class com.yyy.Application --conf spark.executor.instances=1 --conf spark.kubernetes.container.image=docker.io/anantpukale/spark_app:1.3 local://CashFlow-spark2.3.0-shaded.jar下面是堆栈跟踪:

下面是我的docker文件的图像。
错误跟踪表明 docker 中的某物已由命令“ docker ”触发。
dockerfile

Answer 1

我遇到了这个问题。它与Docker镜像ENTRYPOINT相关。在使用Kubernetes的spark 2.3.0中，现在有一个Dockerfile的示例，该示例在kubernetes / dockerfiles /中的ENTRYPOINT中使用特定脚本。如果docker镜像未使用该特定脚本作为ENTRYPOINT，则容器将无法正确启动。 Spark Kubernetes Docker documentation
