peter-toth opened a new pull request, #53142: URL: https://github.com/apache/spark/pull/53142
### What changes were proposed in this pull request? Fix `KeyGroupedShuffleSpec.createPartitioning()` as clustering required at the other side of the join might contain more clustering expressions than the number of expressions in the shuffle spec's `KeyGroupedPartitioning`, so simply zipping them is not correct. ### Why are the changes needed? Fix a correctness issue due to wrong partitioning on the shuffle side. ### Does this PR introduce _any_ user-facing change? Yes, it fixes the query. ### How was this patch tested? Added new UT. ### Was this patch authored or co-authored using generative AI tooling? No. -- This is an automated message from the Apache Git Service.
