When you need to run functions as AGGREGATE or REDUCE (both are aliases), the first parameter is an array value and the second parameter you must define what are your default values and types. You can write 1.0 (Decimal, Double or Float), 0 (Boolean, Byte, Short, Integer or Long) but this leaves Spark the responsibility ...Jun 6, 2022 · (a) Confuses NoneType and None (b) thinks that NameError: name 'NoneType' is not defined and TypeError: cannot concatenate 'str' and 'NoneType' objects are the same as TypeError: 'NoneType' object is not iterable (c) comparison between Python and java is "a bunch of unrelated nonsense" – If a field only has None records, PySpark can not infer the type and will raise that error. Manually defining a schema will resolve the issue >>> from pyspark.sql.types import StructType, StructField, StringType >>> schema = StructType([StructField("foo", StringType(), True)]) >>> df = spark.createDataFrame([[None]], schema=schema) >>> df.show ... class DecimalType (FractionalType): """Decimal (decimal.Decimal) data type. The DecimalType must have fixed precision (the maximum total number of digits) and scale (the number of digits on the right of dot).1 Answer Sorted by: 6 NumPy types, including numpy.float64, are not a valid external representation for Spark SQL types. Furthermore schema you use doesn't reflect the shape of the data. You should use standard Python types, and corresponding DataType directly: spark.createDataFrame (samples.tolist (), FloatType ()).toDF ("x") ShareIt returns "TypeError: StructType can not accept object 60651 in type <class 'int'>". Here you can see better: # Create a schema for the dataframe schema = StructType ( [StructField ('zipcd', IntegerType (), True)] ) # Convert list to RDD rdd = sc.parallelize (zip_cd) #solution: close within []. Another problem for the solution, if I do that .... Mini solar panels
