> Refactor usage of Executor in ExecutorSuite to ensure proper cleanup
> --------------------------------------------------------------------
>
> Key: SPARK-33793
> URL: https://issues.apache.org/jira/browse/SPARK-33793
> Project: Spark
> Issue Type: Bug
> Components: Tests
> Affects Versions: 3.0.1
> Reporter: Sander Goos
> Priority: Major
>
> Recently an issue was discovered that leaked Executors (which are not
> explicitly stopped after a test) can cause other tests to fail due to the JVM
> being killed after 10 min.
> It is therefore crucial that tests always stop the Executor. In most tests
> this is already the case, but to make this pattern more explicit it would be
> good to have a helper function that ensures stopping the executor in a
> finally block.
