Как преобразовать json в spark dataframe

Есть такого типа json:

[ {'count': 308,
  'next': 'some_url',
  'previous': None,
  'results': [{'assigned_to': 43,
    'category': 'Unused',
    'comments': None,
    'completed_ts': None,
    'created': '2019-05-27T05:14:22.306843Z',
    'description': 'Pollution',
    'display_name': {'admin': False,
     'business_name': 'Test Business',
     'contact_number': 'some_number',
     'dob': None,
     'email': 'some_mail',
     'emp_id': None,
     'first_name': 'Alisha'}}]},
  {'count': 309,
  'next': 'some_url',
  'previous': None,
  'results': [{'assigned_to': 44,
    'category': 'Unused',
    'comments': None,
    'completed_ts': None,
    'created': '2019-05-27T05:14:22.306843Z',
    'description': 'Pollution',
    'display_name': {'admin': False,
     'business_name': 'Test Business',
     'contact_number': 'some_number',
     'dob': None,
     'email': 'some_mail',
     'emp_id': None,
     'first_name': 'Ali'}}]},......}]

Необходимо преобразовать его в dataframe
