rmetzger opened a new pull request #14033: URL: https://github.com/apache/flink/pull/14033
## What is the purpose of the change The purpose of this change is to increase the robustness of the e2e tests overall. ## Brief change log - Check of leftover JVMs after a e2e test, and fails if there's one - Check for "more ports open than before", and fail if there are more open - increase robustness of process stopping: wait until a process has finished, potentially shooting it with a sigkill - increase robustness of `run_with_timeout`. It used to leave a dangling `sleep` in the system ## Verifying this change I ran this change through 3 CI runs, to make sure all the tests adhere to the stricter requirements of "no leftover stuff". I will also manually test the watchdog again (proper killing and reporting). ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
