> {{TestDistributedShell}} times out on trunk. I found that the application, and containers will stay running in the background long after the unit test has failed.
> This causes failure of other test cases and several false positives failures as result of:
> * Ports will stay busy, so other tests cases fail to launch.
> * Unit tests fail because of memory restrictions.
> Although the unit test is already broken on trunk, we do not want its failures to other unit tests.
> {{TestDistributedShell}} needs to be revisited to make sure that all {{YarnClients}}, and {{YarnApplications}} are closed properly at the end of the each unit test (including exception and timeouts)
> Steps to reproduce:
> {code:bash}
> mvn test -Dtest=TestDistributedShell#testDSShellWithOpportunisticContainers
> ## this will timeout as
