HyukjinKwon opened a new pull request #29229: URL: https://github.com/apache/spark/pull/29229
### What changes were proposed in this pull request? This PR removes the manual port of `heapq3.py` introduced from SPARK-3073. The main reason of this was to support Python 2.6 and 2.7 because Python 2's heapq.merge() do not support `key` and `reverse`. See - https://docs.python.org/2/library/heapq.html#heapq.merge in Python 2 - https://docs.python.org/3.8/library/heapq.html#heapq.merge in Python 3 Since we dropped the Python 2 at SPARK-32138, we can remove this away. ### Why are the changes needed? To remove unnecessary codes. Also, we can leverage bug fixes made in Python 3.x at `heapq`. ### Does this PR introduce _any_ user-facing change? No, dev-only. ### How was this patch tested? Existing tests should cover. I locally ran and verified: ```bash ./python/run-tests --python-executable=python3 --testname="pyspark.tests.test_shuffle" ./python/run-tests --python-executable=python3 --testname="pyspark.shuffle ExternalSorter" ``` ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
