You shouldn't need to use exlode, that will create a new row for each value in the array. The reason max isn't working for your dataframe is because it is trying to find the max for that column for every row in you dataframe and not just the max in the array. ...
Developers who prefer Python can use PySpark, the Python API for Spark, instead of Scala. Data science workflows that blend data engineering andmachine learningbenefit from the tight integration with Python tools such aspandas,NumPy, andTensorFlow. Enter the following command to start the PySpark sh...
