> Key: YARN-7771
> URL: https://issues.apache.org/jira/browse/YARN-7771
> Project: Hadoop YARN
> Issue Type: Bug
> Components: test
> Reporter: Shane Kumpf
> Priority: Minor
>
> While working on YARN-5428, Pre-commit testing failed due to {{TestDistributedShell#testDSShellWithoutDomainV2DefaultFlow}}. It appears that the tests that rely on {{TestDistributedShell#testDSShell}} are flaky, as I've been able to trigger the failure with several of the tests that leverage that logic.
