> Flaky local YARN tests relying on log files

> Key: FLINK-24169
> URL: https://issues.apache.org/jira/browse/FLINK-24169
> Project: Flink
> Issue Type: Bug
> Components: Deployment / YARN
> Reporter: Matthias Pohl
> Assignee: Zsombor Chikán
> Priority: Major
> Labels: pull-request-available, stale-assigned, test-stability
> Fix For: 1.15.0

> While working on [PR #16989|https://github.com/apache/flink/pull/16989] for
> FLINK-23611, we experienced some flakiness when running
> {{YARNSessionCapacitySchedulerITCase.testDetachedPerJobYarnCluster}} locally.
> [~dmvk] discovered a bug in log4j (see
> [LOG4J2-3155|https://issues.apache.org/jira/browse/LOG4J2-3155]). The bug
> affects the test because they check the log files for specific log messages.
> The log messages ends up in the wrong log file if the rolling update
> mechanism is trigger. This does not seem to be an issue on AzureCI due to the
> slower hardware used for the worker machines.
> A solution to overcome this issue would be to add a custom log4j
> configuration that disables the {{appender.main.policies.startup.type =
> OnStartupTriggeringPolicy}} which is present in {{flink-dist}}'s log4j
> configuration.
