Flaky test dashboard #20437

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.

This dashboard tracks failed push-triggered jobs on master (Static Checks CI, CodeQL, Unit & Integration tests CI). Each problem has its own Flaky test tracking issue with the root cause, suggested fix and full occurrence history. The routine rewrites this body every day and never comments here.

Yesterday (2026-10-10)

• 3 of 7 master commits had failed jobs, one job each: 66504db (build(deps): bump fabric8.version from 7.9.0 to 8.0.0 #20532), 2144e34 (build(deps): bump software.amazon.kinesis:amazon-kinesis-client from 3.5.2 to 3.5.3 #20533) and 7921967 (build(deps): bump org.asynchttpclient:async-http-client from 3.0.13 to 3.0.14 #20535). All three are Dependabot bumps; each failing job passed on the neighbouring commits.
• New: Flaky test: MSQWorkerFaultToleranceTest.test_cancelledWorker_isRetried_ifFaultToleranceIsEnabled #20554 (MSQWorkerFaultToleranceTest.test_cancelledWorker_isRetried_ifFaultToleranceIsEnabled: the controller did not finish within the default 10 s wait after the cancelled worker was relaunched).
• Recurred: Flaky test: QueryVirtualStorageTest.testQueryTooMuchData #20550 (QueryVirtualStorageTest.testQueryTooMuchData, same line-166 message assertion; fixed by test: fix flaky QueryVirtualStorageTest.testQueryTooMuchData #20552, merged 2026-10-11), Flaky test: KinesisFaultToleranceTest.test_supervisorRecovers_afterChangeInTopicPartitions_withEmptyShards #20434 (KinesisFaultToleranceTest.test_supervisorRecovers_afterChangeInTopicPartitions_withEmptyShards, 240 s timeout waiting for published rows).
• Failed once and passed on retry, so the job did not fail and they are not tracked: ReservoirSegmentSamplerTest.testSegmentsFromAllServersAreEquallyLikelyToBePicked (2 commits: 165e9b9, 570 vs expected 625; 98bbcb4, 1354 vs expected 1250), EmbeddedDimensionValueSetShardSpecTest (c59ba76, test_noPartitioning_scansAllSegments_unlikePruned scanned 4 of 5 segments; 2144e34, test_twoSupervisors_withPartitionDimensionValues_segmentsPublishAndQueriesSucceed timed out after 10 s), KinesisIndexTaskTest (98bbcb4, testRestore hit the 120 s timeout; a68ba10, testRestoreAfterPersistingSequences task FAILED), MultiPhaseParallelIndexingRowStatsTest.testHashPartitionRowStats (c59ba76, 1 of 10 subtasks failed), KafkaSupervisorTest.testCheckpointForInactiveTaskGroup (66504db; long-standing Transient failure of KafkaSupervisorTest.testCheckpointForInactiveTaskGroup #6296), WorkerSketchFetcherTest.test_SequentialRetryDisabled_multipleFailures (2144e34, failed twice and passed on the third run).
• No regressions caused by a commit.
