I am the [Flink Jira Bot|https://github.com/apache/flink-jira-bot/] and I help
the community manage its development. I see this issues has been marked as
Minor but is unassigned and neither itself nor its Sub-Tasks have been updated
for 180 days. I have gone ahead and marked it "stale-minor". If this ticket is
still Minor, please either assign yourself or give an update. Afterwards,
please remove the label or in 7 days the issue will be deprioritized.

>
> Key: FLINK-25514
> URL: https://issues.apache.org/jira/browse/FLINK-25514
> Project: Flink
> Issue Type: Bug
> Components: Deployment / YARN
> Affects Versions: 1.15.0, 1.13.5, 1.14.2
> Reporter: Niklas Semmler
> Priority: Minor
> Labels: stale-minor, test-stability
>
> Many YARN tests that inherit from _org.apache.flink.yarn.YarnTestBase_ deploy
> a Flink cluster via YARN. The class provides the method
> _ensureNoProhibitedStringInLogFiles_ to scans the Flink cluster log files for
> exceptions.
> At its current state the method cannot distinguish between log files from
> different test cases that are part of the same test class. (E.g.,
> _org.apache.flink.yarn.YARNSessionFIFOSecuredITCase#testDetachedModeSecureWithPreInstallKeytab_
> and
> {_}org.apache.flink.yarn.YARNSessionFIFOSecuredITCase#testDetachedMode{_})
> Thereby, test cases fail only due to a failure of an earlier test case.
> (E.g., _testDetachedMode_ fails due to a failure of
> {_}testDetachedModeSecureWithPre{_}{_}InstallKeytab{_})
> The filtering method should be improved, to make failures better
> understandable. To this end, the filtering method needs to filter on the
> container suffix of the path. For the YARN container name
> _container_1640947393046_0001_01_000001_ it needs to map the _0001_ part to
> the number of the test case considering only test cases that spawn clusters.
> Or/and the naming of the containers need to be adapted to make this easier.
> An alternative solution would be to start one YARN cluster per test case
> (instead of as per test class).
