-------------------------------
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.
