             Summary: Run UnalignedCheckpointTestBase with DefaultScheduler instead of skipping it under AdaptiveScheduler
                 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


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.
