This issue was reviewed as part of the JIRA-migrated backlog triage (HUDI-8457). **Findings: needs a reproduction against a current build before it can be dispositioned.** The report is concrete and actionable as written: a MERGE INTO whose extra MATCHED condition references the target table (t.department = s.department, or even t.department = 'A') fails, while the same condition on the source alias alone works. I have deliberately not called this one from the source. The surrounding code has been substantially rewritten since it was filed - table versions 8 and 9, the `BufferedRecordMerger` family replacing payload-based merging, the file-group-reader migration, and the `hudi-common` package reorganisations in #19193 / #19195. With that much churn, inferring either "still broken" or "silently fixed" would be a guess rather than a finding, and both errors are costly here. The good news is that reproducing it is cheap: the MERGE INTO statements in the description are self-contained and isolate the failure to the target-table reference in the AND clause. There is also no commit anywhere in the tree referencing HUDI-8457, so if this was fixed it was incidental to another change rather than deliberate - which is another reason to verify rather than assume.
