> Affects Versions: 2.4.0, 2.4.1, 2.4.2, 2.4.3
> Reporter: Hyukjin Kwon

> {code}
> ./bin/pyspark --conf spark.driver.maxResultSize=1m
> spark.conf.set("spark.sql.execution.arrow.enabled",True)
> spark.range(10000000).toPandas()
> {code}
> The codes above returns an empty dataframe in Spark 2.4 but It should throw an exception as below:
> {code}
> py4j.protocol.Py4JJavaError: An error occurred while calling o31.collectToPython.
> : org.apache.spark.SparkException: Job aborted due to stage failure: Total size of serialized results of 1 tasks (3.0 MB) is bigger than spark.driver.maxResultSize (1024.0 KB)

> This is a regression between Spark 2.3 and 2.4.
> This JIRA targets to add a regression test.
> In Spark 2.4:
> {code}
> ./bin/pyspark --conf spark.driver.maxResultSize=1m
> spark.conf.set("spark.sql.execution.arrow.enabled",True)
> spark.range(10000000).toPandas()
> {code}
> {code}

> {code}
> or it can return partial results:
> {code}
