Yicong-Huang opened a new pull request, #53708: URL: https://github.com/apache/spark/pull/53708
### What changes were proposed in this pull request? Remove a redundant `_accumulatorRegistry.clear()` call in `worker.py`. Currently there are two consecutive `clear()` calls with no accumulator-modifying code in between: ```python shuffle.MemoryBytesSpilled = 0 shuffle.DiskBytesSpilled = 0 _accumulatorRegistry.clear() # first call setup_spark_files(infile) setup_broadcasts(infile) _accumulatorRegistry.clear() # second call ``` Neither `setup_spark_files` nor `setup_broadcasts` adds anything to `_accumulatorRegistry`, so the first `clear()` is redundant. ### Why are the changes needed? This is dead code cleanup. The redundant call was introduced when: - SPARK-3463 (2014) added the first `clear()` after shuffle initialization - SPARK-3030 (2014) added the second `clear()` after broadcasts setup - SPARK-44533 (2023) refactored to extract `setup_spark_files` and `setup_broadcasts`, but preserved both `clear()` calls ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? Existing tests. This is a simple dead code removal with no functional change. ### Was this patch authored or co-authored using generative AI tooling? Yes. -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
