> Key: FLINK-40484
> URL: https://issues.apache.org/jira/browse/FLINK-40484
> Project: Flink
> Issue Type: Technical Debt
> Components: Runtime / Checkpointing, Tests
> Reporter: Rui Fan
> Assignee: Rui Fan
> Priority: Major
> Labels: pull-request-available
> Fix For: 2.4.0
>
>
> UnalignedCheckpointTestBase is annotated with
> @Category(FailsWithAdaptiveScheduler) (added in FLINK-21101). When the
> enable-adaptive-scheduler profile is active, surefire excludes this category,
> so the whole suite is skipped entirely rather than run.
> These are exactly the kind of tests that benefit from being exercised as
> often as possible — the more they run, the more likely intermittent issues
> surface. Skipping the suite whenever the adaptive-scheduler profile is on
> unnecessarily reduces how often it runs and lowers coverage.
> Since the suite is only expected to fail under the AdaptiveScheduler (not
> with the DefaultScheduler), we don't need to skip it. Instead we can pin
> JobManagerOptions.SCHEDULER = Default in the test's job configuration and
> drop the category exclusion. The suite then always runs with the
> DefaultScheduler, regardless of which scheduler the CI profile selects —
> increasing coverage and giving more chances to catch flakiness, without ever
> running it under the unsupported AdaptiveScheduler.
> Proposed change:
> - Set JobManagerOptions.SCHEDULER = Default in
> UnalignedCheckpointTestBase#getConfiguration.
> - Remove @Category(FailsWithAdaptiveScheduler) and the now-unused imports.
