_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:** `KafkaClusterMetricsTest` (`test_ingest10kRows_ofSelfClusterMetrics_andVerifyValues`, `test_ingestClusterMetrics_withConcurrentCompactionSupervisor_andKillUnusedSegments`) (embedded-tests, `unit tests / unit tests(main) (25, K*,U*,Z*,Y*,X*)`) **Failures:** 1 · **First seen:** 2026-10-14 · **Last seen:** 2026-10-14 ### Root cause Both tests timed out after the 60 s `useDefaultTimeoutForLatchableEmitter(60)`: one waiting for 10 `ingest/handoff/count` events (line 181), the other (MSQ compaction variant) waiting for the first `task/success/count` (line 229). The tests ingest the cluster's own metrics through the Kafka emitter, so their progress depends on the metric emission rate and on task scheduling on a busy runner. In the same job, the preceding `KinesisFaultToleranceTest` also failed on slow publishing. The commit (#20577) only bumps GitHub Actions versions, the re-run attempt passed this class in 68 s, and the next master commit was green. ### Suggested fix Give these waits an explicit, larger timeout (for example 120 s, matching the method `@Timeout(120)`) instead of the 60 s cluster default. Also lower `expectedSegmentsHandedOff` or `maxRowsPerSegment` so the test needs fewer emitted metrics. ### 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 | |---|---|---|---|---|---| | 2026-10-14 | afe71f5381 (#20577) | `unit tests / unit tests(main) (25, K*,U*,Z*,Y*,X*) / test-jdk25-[K*,U*,Z*,Y*,X*]` | [job 115925729106](https://github.com/apache/druid/actions/runs/38585343856/job/115925729106) | both tests: `ISE: Timed out waiting for event after [60,000]ms` (lines 181 and 229, MSQ variant `[2]`); 1/1 attempt; run attempt 1 | | -- This is an automated message from the Apache Git Service.
