在spark集群上执行python应用程序时，遇到以下异常：

Using Spark's default log4j profile: org/apache/spark/log4j-defaults.properties
Setting default log level to "WARN".
To adjust logging level use sc.setLogLevel(newLevel). For SparkR, use setLogLevel(newLevel).

不知何故，集群（在同一网络中的远程PC上）尝试访问本地python（安装在执行驱动程序的本地工作站上）：

Caused by: java.io.IOException: Cannot run program "C:\Users\<local-user>\Anaconda2\python.exe": CreateProcess error=2, The system cannot find the file specified
  • Spark 2.1.0
  • Spark独立群集正在Windows 10上运行
  • 工作站在Windows 7上运行
  • 使用spark-shell（交互式）连接到群集并执行任务可以正常工作
  • 使用pyspark（交互式）连接到群集并执行任务可以正常工作
  • 直接从pycharm运行导致上面的异常
  • 使用spark-submit执行导致类似问题（=＆gt;尝试访问我的本地python）
  • 正在使用findspark
  • 设置了PYSPARK_PYTHON和PYSPARK_DRIVER_PYTHON环境变量
  • 集群和工作站上的Python：Python 2.7.13 :: Anaconda custom（64位）

提前感谢您的帮助

答案 0 :(得分：1)

所以我现在找到了解决问题的方法。对于我的设置，问题是findspark库。删除允许我在群集上运行我的所有任务。

如果你有类似的问题，但它没有找到相关的问题，我会指出你上面的Samson Scharfrichter的评论。
