             Summary: `returnType` attribute of UDF when the user-specified return type has column name embeded
                 Key: SPARK-42247
                 URL: https://issues.apache.org/jira/browse/SPARK-42247
             Project: Spark
          Issue Type: Sub-task
          Components: Connect, PySpark
    Affects Versions: 3.4.0
            Reporter: Xinrong Meng


The inconsistency can be reproduced as shown below:

{code}
# connect
>>> pandas_udf(lambda x : x + 1, "id int").returnType
IntegerType()

# vanilla PySpark
>>> pandas_udf(lambda x : x + 1, "id int").returnType
StructType([StructField('id', IntegerType(), True)])
{code}
