[rangareddy]

This issue was reviewed as part of the JIRA-migrated backlog triage (HUDI-9161).

Findings: still open.

The body is boilerplate or a single line, so the title carries the whole specification - there are no acceptance criteria to verify against, and nothing a contributor could pick up without reconstructing the intent.

No commit referencing HUDI-9161 exists in the tree, so nothing has landed under this ticket's key.

If this is still wanted, the most useful addition would be a short statement of what "done" looks like. If it is not, it is a candidate for closing during backlog cleanup rather than carrying indefinitely.

Keeping this open.
