[I] Flaky test: multi-stage-query.spec.ts "runs a query that reads external data" (web-console e2e) (druid)
FrankChen021 opened a new issue, #20438:
URL: https://github.com/apache/druid/issues/20438
_This issue was generated automatically by Claude Code (Anthropic's AI coding agent) running a scheduled CI-triage routine on behalf of @FrankChen021. Analysis and suggested fixes are AI-produced; please verify before acting on them._
**Status:** Open: no fix PR
**Subject:** `multi-stage-query.spec.ts` › `runs a query that reads external data` (web-console e2e, `web-checks`)
**Failures:** 2 · **First seen:** 2026-09-26 · **Last seen:** 2026-09-26
### Root cause
Race between e2e specs: `auto-compaction.spec.ts` runs just before this spec and leaves its compaction config active, so a compaction task can still hold one of the two task slots. The MSQ query asks for 2 tasks, so the workbench shows the `CapacityAlert` dialog ("current usage: 1 of 2 … Run it anyway"). `WorkbenchOverview.runQuery` never confirms that dialog and then waits 240 s for `div.result-table-pane`. The error screenshots from both failures show this dialog. Both failures ran concurrently on 0387ffa902 and 017c18ab6d; neither commit touches the web console, and the next master commit (e16bbf8bdc) passed. An older report of the same symptom is #13115.
### Suggested fix
In `web-console/e2e-tests/component/workbench/overview.ts`, click `Run it anyway` in `runQuery` when the capacity alert appears. Alternatively, have `auto-compaction.spec.ts` delete its compaction config and wait for running tasks to finish before it exits.
### Occurrences
Failed push-triggered master jobs only. The daily triage routine adds one row per new failed job.
