> Key: SPARK-31386
> URL: https://issues.apache.org/jira/browse/SPARK-31386
> Project: Spark
> Issue Type: Bug
> Components: PySpark
> Affects Versions: 2.4.4
> Environment: Spark 2.4.4 or AWS EMR
> `pyspark --conf spark.executor.pyspark.memory=500m`
> Reporter: Viacheslav Krot

> Following code with udf causes MemoryError when
> `spark.executor.pyspark.memory` is set
> ```
> from pyspark.sql.types import BooleanType
> from pyspark.sql.functions import udf
> df = spark.createDataFrame([
> ('Alice', 10),
> ('Bob', 12)
> ], ['name', 'cnt'])
> broadcast = spark.sparkContext.broadcast([1,2,3])
> @udf(BooleanType())
> def f(cnt):
> return cnt < len(broadcast.value)
> df.filter(f(df.cnt)).count()
> ```
> Same code work well when spark.executor.pyspark.memory is not set.
> The code by itself does not make any sense, just simplest code to reproduce
> the bug.

> Error:
