Handling Empty DataFrames when Applying Pandas UDFs to PySpark DataFrames
PySpark DataFrame Pandas UDF Returns Empty DataFrame Understanding the Problem When working with PySpark DataFrames and Pandas UDFs, it’s not uncommon to encounter issues with data processing and manipulation. In this case, we’re dealing with a specific problem where the Pandas UDF returns an empty DataFrame, which conflicts with the defined schema. The question arises from applying a Pandas UDF to a PySpark DataFrame for filtering using the groupby('Key').apply(UDF) method. The UDF is designed to return only rows with odd numbers in the ‘Number’ column, but sometimes there are no such rows in a group, resulting in an empty DataFrame being returned.
