【问题描述】：
我可以在本地 PC 上运行“spark-shell”。 但是我不能让 pyspark 在 PC 上运行，错误附在日志中。
我也在很多地方搜索过，但这并没有解决我的问题。 任何有 PySpark 经验的人都可以启发我的路径。提前谢谢你。
我的配置：
- 火花：3.2.0
- Java 17
- Python 3.8.6
Python 3.8.6 (tags/v3.8.6:db45529, Sep 23 2020, 15:52:53) [MSC v.1927 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
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).
