### What changes were proposed in this pull request? This follow-up fixes an issue when inserting key/value pairs into `IdentityHashMap` in `SubExprEvaluationRuntime`. ### Why are the changes needed? The last commits to #30341 follows review comment to use `IdentityHashMap`. Because we leverage `IdentityHashMap` to compare keys in reference, we should not convert expression pairs to Scala map before inserting. Scala map compares keys by equality so we will loss keys with different references. ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested? Run benchmark to verify. Closes #30459 from viirya/SPARK-33427-map. Authored-by: Liang-Chi Hsieh <viirya@gmail.com> Signed-off-by: HyukjinKwon <gurwls223@apache.org> |
