    Description copied from interface: SplitHintSpec
    
    Returns an iterator of splits. A split has a list of files of the type SplitHintSpec.
    
    Specified by:
    
    split in interface SplitHintSpec
    
    Parameters:
    
    inputIterator - that returns input files.
    
    inputAttributeExtractor - to create InputFileAttribute for each input file. This may involve a network call, so implementations of SplitHintSpec should use it only if needed, and reuse results if appropriate.
