> Invalid PythonUDF - requires attributes from more than one child - in "on" join condition
> -----------------------------------------------------------------------------------------
>
> Key: SPARK-25314
> URL: https://issues.apache.org/jira/browse/SPARK-25314
> Project: Spark
> Issue Type: Bug
> Components: PySpark, SQL
> Affects Versions: 2.3.1
> Reporter: Sergey Bahchissaraitsev
> Priority: Major
>
> This is another variation of the SPARK-19728 which was tagged as resolved. So I base the example on it:
> from pyspark.sql.functions import udf
> from pyspark.sql.types import BooleanType
> df1 = sc.parallelize([(1, ), (2, )]).toDF(["col_a"])
> df2 = sc.parallelize([(2, ), (3, )]).toDF(["col_b"])
> pred = udf(lambda x, y: x == y, BooleanType())
> df1.join(df2, pred(df1.col_a, df2.col_b)).show()
> This throws:
> {quote}java.lang.RuntimeException: Invalid PythonUDF <lambda>(col_a#132L, col_b#135L), requires attributes from more than one child.
