Hongze Zhang created SPARK-55979:
------------------------------------
Summary: Required input attributes are missing from PartialMerge /
Final BaseAggregateExec.references
Key: SPARK-55979
URL: https://issues.apache.org/jira/browse/SPARK-55979
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 4.1.1
Reporter: Hongze Zhang
In some cases, aggregate's required attributes are not present in
aggregate.references, which is likely a bug:
!image-2026-03-12-19-29-56-189.png|width=547,height=179!
In the debug screenshot, parent is a HashAggregateExec, which needs sum#1207L /
sum#1208L as intermediate input. However, they are not present in `.references`
call, producing unreliability for further work relying on `.references` call.
