为什么 pyspark 失败并显示“实例化‘org.apache.spark.sql.hive.HiveSessionStateBuilder’时出错”？

我一生都无法弄清楚我的 PySpark 安装出了什么问题。我已经安装了所有依赖项，包括 Hadoop，但 PySpark 找不到它——我的诊断是否正确？

请参阅下面的完整错误消息，但它最终在 PySpark SQL 上失败

pyspark.sql.utils.IllegalArgumentException: u"Error while instantiating 'org.apache.spark.sql.hive.HiveSessionStateBuilder':"

tl;dr关闭所有其他 Spark 进程并重新开始。

以下 WARN 消息表示有另一个进程（或多个进程）持有该端口。

我确信这些进程是 Spark 进程，例如pyspark 会话或 Spark 应用程序。

这就是为什么 Spark/pyspark 发现端口 4044 可免费用于 Web UI 后尝试实例化HiveSessionStateBuilder并失败了。

pyspark 失败，因为您无法启动并运行多个使用同一本地 Hive 元存储的 Spark 应用程序。
