> Tear down installed software in reverse order in Jepsen tests. This mitigates
> the issue that sometimes YARN's NodeManager directories cannot be removed
> using {{rm -rf}} because Flink processes keep running and generate files
> after the YARN NodeManager is shut down. {{rm -r}} removes files recursively
> but if files are created in the background concurrently, the command can
> still fail with a non-zero exit code.
