为什么pyspark失败并显示“实例化'org.apache.spark.sql.internal.SessionStateBuilder时出错”？

标签： java apache-spark pyspark pycharm databricks

在尝试通过PyCharm（通过带有AWS的Databricks）启动Pyspark并运行时，出现以下错误：

Spark service enabled. To enable the Spark service on this cluster, go to
https://....cloud.databricks.com/?o=...#setting/clusters//#setting/clusters/.../configuration
and add the following to the cluster's Spark config:

spark.databricks.service.server.enabled true

我将其设置为true。我什至在Databricks上设置了一个新集群，最初将其设置为true，但仍然收到相同的错误！

完整错误消息：

During handling of the above exception, another exception occurred:

我已将配置变量spark.databricks.service.server.enabled设置为true，但仍然收到此错误。

将您的PyCharm更新到最新版本。我之前遇到过同样的问题。
