      Description

      Pyspark's cloudpickle.py and versions of cloudpickle below 1.3.0 interfere with dill unpickling because they define types.ClassType, which is undefined in dill. This results in the following error:

      Traceback (most recent call last):
        File "/usr/local/lib/python3.6/site-packages/apache_beam/internal/pickler.py", line 279, in loads
          return dill.loads(s)
        File "/usr/local/lib/python3.6/site-packages/dill/_dill.py", line 317, in loads
          return load(file, ignore)
        File "/usr/local/lib/python3.6/site-packages/dill/_dill.py", line 305, in load
          obj = pik.load()
        File "/usr/local/lib/python3.6/site-packages/dill/_dill.py", line 577, in _load_type
          return _reverse_typemap[name]
      KeyError: 'ClassType'

      (See https://github.com/cloudpipe/cloudpickle/issues/82)

      This was fixed for cloudpickle 1.3.0+ (https://github.com/cloudpipe/cloudpickle/pull/337), but PySpark's cloudpickle.py doesn't have this change yet.
