【问题描述】：
我正在尝试 Pandas UDF 并面临 IllegalArgumentException。我还尝试从 PySpark 文档 GroupedData 复制示例进行检查，但仍然收到错误。
以下是环境配置
- python3.7
- 使用 pip 安装 PySpark==2.4.5
- 使用 pip 安装 PyArrow==0.16.0
from pyspark.sql.functions import pandas_udf, PandasUDFType
@pandas_udf('int', PandasUDFType.GROUPED_AGG)
def min_udf(v):
return v.min()
sorted(gdf.agg(min_udf(df.age)).collect())
输出
Py4JJavaError Traceback (most recent call last)
