> spark.createDataFrame won't work with non-nullable schema as below:
> {code:java}
> from pyspark.sql.types import *
> schema_false = StructType([StructField("id", IntegerType(), False)])
> spark.createDataFrame([[1]], schema=schema_false)
> Traceback (most recent call last):

> pyspark.errors.exceptions.connect.AnalysisException: [NULLABLE_COLUMN_OR_FIELD] Column or field `id` is nullable while it's required to be non-nullable.{code}
> whereas it works fine with nullable schema:

> schema_true = StructType([StructField("id", IntegerType(), True)])
> spark.createDataFrame([[1]], schema=schema_true)
> DataFrame[id: int]{code}
