  1. The Python error type is lost when reporting task status from the worker to the driver.
  2. Task streams cannot be read multiple times. (See test_self_join in test_parity_pandas_map.py.)
  3. Repartition does not work in some situations. (See test_dataframes_with_more_columns in test_parity_pandas_map.py.)
