-------------------------------------

             Summary: createDataFrame() reorders row
                 Key: SPARK-27712
                 URL: https://issues.apache.org/jira/browse/SPARK-27712
             Project: Spark
          Issue Type: Bug
          Components: PySpark
    Affects Versions: 2.4.0
         Environment: emr-5.20.0

PySpark 2.4.0

Python 2.7.15
            Reporter: Tim Ludwinski


Executing  the following:
{code:java}
my_schema = pyspark.sql.types.StructType([
    pyspark.sql.types.StructField("B", pyspark.sql.types.StringType(), True),
    pyspark.sql.types.StructField("A", pyspark.sql.types.StringType(), True)
])

spark.createDataFrame(spark.sparkContext.parallelize([pyspark.sql.Row(A="1", B="2")]), my_schema).collect()
{code}
should produce this:
{code:java}
[Row(A="1", B="2")]
{code}
or this:
{code:java}
[Row(B='2', A='1')]
{code}
but produces this instead:
{code:java}
[Row(B=u'1', A=u'2')]
{code}
