On a busy runner, `ingest/rows/published` did not reach 2000 within 240 s, and the timeout message does not say whether the tasks were stuck or just slow. ### Suggested fix Wait for the supervisor to report 4 partitions before waiting on the row aggregate, and log the supervisor status and the current row sum on timeout. ### Occurrences Failed push-triggered master jobs only. The daily triage routine adds one row per new failed job. | Date | Commit | Job | Failure log | Detail | Reported in | |---|---|---|---|---|---| | 2026-09-23 | 4eede66fcf (#20380) | `unit tests (25, K*,U*,Z*,Y*,X*)` | [job 106878085304](https://github.com/apache/druid/actions/runs/35766742278/job/106878085304) | timed out after 240 s waiting for 2000 published rows; 1/1 attempt | #20414 | -- This is an automated message from the Apache Git Service.
