> As of 1.2.0, Python tests take around 10-12 minutes to run. Once [SPARK-3431] is complete, this will become a significant fraction of the total test time.
> There are 2 separate approaches to explore for parallelizing the execution of Python unit tests:
> * Use GNU parallel to run each Python test file in parallel.
> * Use [{{nose}}|http://nose.readthedocs.org/en/latest/doc_tests/test_multiprocess/multiprocess.html] to parallelize all Python tests in a more extensible/configurable way.
