Spark Mesos 集群在执行器中为 spark-class 设置了错误的路由

Question

我有一个 flask API，它使用 pyspark 启动 spark 并将作业发送到 mesos 集群。

执行器失败，因为它正在执行 spark-class 在 Flask API.

中的路径

粗体路径是spark-class实际在Flask服务器（作业的请求者）中的部分

sh: /home/user/source/environment/lib/python3.7/site-packages/pyspark/./bin/spark-class: 没有那个文件或目录

这里：

-rwxr-xr-x 1 root root 3.2K Sep  1 11:07 /home/user/source/environment/lib/python3.7/site-packages/pyspark/bin/spark-class

也许我缺少环境变量，或者我可以将路径作为参数发送吗？

通过添加指向 Spark 二进制文件的属性将 spark 所在的路径添加到执行器中来解决：

spark.mesos.executor.home
