> Make it easier to convert numpy arrays to dataframes.
> Often we receive errors:
>
> {code:java}
> df = spark.createDataFrame(numpy.arange(10))
> Can not infer schema for type: <class 'numpy.int64'>
> {code}
>
> OR
> {code:java}
> df = spark.createDataFrame(numpy.arange(10.))
> Can not infer schema for type: <class 'numpy.float64'>
> {code}
>
> Today (Spark 3.x) we have to:
> {code:java}
> spark.createDataFrame(pd.DataFrame(numpy.arange(10.))) {code}
> Make this easier with a direct conversion from Numpy arrays to Spark
> Dataframes.
