From ca910a3c1e2eb78dc2ca9f048f00ee0c3e872c4b Mon Sep 17 00:00:00 2001 From: Dongjoon Hyun Date: Wed, 3 May 2023 07:01:12 -0700 Subject: [PATCH] [SPARK-43348][PYTHON] Support `Python 3.8` in PyPy3 ### What changes were proposed in this pull request? This PR aims two goals. 1. Make PySpark support Python 3.8+ with PyPy3 2. Upgrade PyPy3 to Python 3.8 in our GitHub Action Infra Image to enable test coverage Note that there was one failure at `test_create_dataframe_from_pandas_with_day_time_interval` test case. This PR skips the test case and SPARK-43354 will recover it after further investigation. ### Why are the changes needed? Previously, PySpark fails at PyPy3 `Python 3.8` environment. ``` pypy3 version is: Python 3.8.16 (a9dbdca6fc3286b0addd2240f11d97d8e8de187a, Dec 29 2022, 11:45:13) [PyPy 7.3.11 with GCC 10.2.1 20210130 (Red Hat 10.2.1-11)] Starting test(pypy3): pyspark.sql.tests.pandas.test_pandas_cogrouped_map (temp output: /__w/spark/spark/python/target/f1cacde7-d369-48cf-a8ea-724c42872020/pypy3__pyspark.sql.tests.pandas.test_pandas_cogrouped_map__rxih6dqu.log) Traceback (most recent call last): File "/usr/local/pypy/pypy3.8/lib/pypy3.8/runpy.py", line 188, in _run_module_as_main mod_name, mod_spec, code = _get_module_details(mod_name, _Error) File "/usr/local/pypy/pypy3.8/lib/pypy3.8/runpy.py", line 111, in _get_module_details __import__(pkg_name) File "/__w/spark/spark/python/pyspark/__init__.py", line 59, in from pyspark.rdd import RDD, RDDBarrier File "/__w/spark/spark/python/pyspark/rdd.py", line 54, in from pyspark.java_gateway import local_connect_and_auth File "/__w/spark/spark/python/pyspark/java_gateway.py", line 32, in from pyspark.serializers import read_int, write_with_length, UTF8Deserializer File "/__w/spark/spark/python/pyspark/serializers.py", line 69, in from pyspark import cloudpickle File "/__w/spark/spark/python/pyspark/cloudpickle/__init__.py", line 1, in from pyspark.cloudpickle.cloudpickle import * # noqa File "/__w/spark/spark/python/pyspark/cloudpickle/cloudpickle.py", line 56, in from .compat import pickle File "/__w/spark/spark/python/pyspark/cloudpickle/compat.py", line 13, in from _pickle import Pickler # noqa: F401 ModuleNotFoundError: No module named '_pickle' ``` To support Python 3.8 in PyPy3. - From PyPy3.8, `_pickle` is removed. - https://github.com/cloudpipe/cloudpickle/issues/458 - We need this change. - https://github.com/cloudpipe/cloudpickle/pull/469 ### Does this PR introduce _any_ user-facing change? This is an additional support. ### How was this patch tested? Pass the CIs. Closes #41024 from dongjoon-hyun/SPARK-43348.
