pyspark - Databricks PySpark 作业不断被取消

Question

我在 Azure 上使用 Databricks 笔记本，我有一个完美的 Pyspark 笔记本，昨天一整天都运行良好。但是在一天结束时，我注意到我在之前知道可以正常工作的代码上遇到了一些奇怪的错误:org.apache.spark.SparkException: Job aborted due to stage failure: Task from application
但因为太晚了，我把它留到今天。今天我尝试创建一个新的集群并运行代码，这次它一直说我的工作被“取消”

事实上，我只是尝试运行 1 行代码:

filePath = "/SalesData.csv"

甚至被取消了。

编辑:

这是来自 Azure 的 std 错误日志:

我和我的团队在安装 azureml['notebooks'] 后遇到了这个问题。 Python 打包到我们的集群中。安装似乎有效，但我们在尝试运行代码单元时收到“已取消”消息。

我们还在日志中收到了一个类似于这篇文章中的错误:

The 'config' trait of an IPythonShell instance must be a Config, 
  but a value of class 'IPython.config.loader.Config'...

似乎某些 Python 包可能与此 Config 对象冲突，或者不兼容。我们卸载了库，重新启动了集群，一切正常。希望这对某人有所帮助:)
