将Python UDF应用于Spark数据框时，java.lang.IllegalArgumentException [英] java.lang.IllegalArgumentException when applying a Python UDF to a Spark dataframe

问题描述

我正在测试 pandas_udf 文档中提供的示例代码(

I'm testing the example code provided in the documentation of pandas_udf (https://spark.apache.org/docs/2.3.1/api/python/pyspark.sql.html#pyspark.sql.functions.pandas_udf), using Pyspark 2.3.1 on my local machine:

from pyspark.sql import SparkSession
from pyspark.sql.functions import pandas_udf, PandasUDFType
df = spark.createDataFrame(
    [(1, 1.0), (1, 2.0), (2, 3.0), (2, 5.0), (2, 10.0)],
    ("id", "v"))  
@pandas_udf("id long, v double", PandasUDFType.GROUPED_MAP)  
def normalize(pdf):
    v = pdf.v
    return pdf.assign(v=(v - v.mean()) / v.std())
df.groupby("id").apply(normalize).show()  

但是，当我这样做时，我引发了一个 java.lang.IllegalArgumentException (完整的堆栈跟踪显示在本文下方).

But when I do so I raise a java.lang.IllegalArgumentException (full stacktrace shown below this post).

知道我在做什么错吗?

推荐答案

根据>://issues.apache.org/jira/browse/SPARK-29367 ，您需要:

• 设置环境变量

ARROW_PRE_0_15_IPC_FORMAT=1

• 或使用早于 0.15 的 pyarrow 版本，例如 0.14.1
• or use a version of pyarrow older than 0.15, e.g. 0.14.1
