Review Comment:
It might be better to avoid using `Thread.sleep` in test cases, as it may
increase the duration of CI and behave as flaky tests. How about introduce a
`TestScheduledThreadPoolExecutor` so we can control when each step is
triggered? An example of this is
`org.apache.flink.util.concurrent.ManuallyTriggeredScheduledExecutor`.
