rmetzger opened a new pull request #15417: URL: https://github.com/apache/flink/pull/15417
## What is the purpose of the change This commit fixes a test instability in ReactiveModeITCase.testScaleDownOnTaskManagerLoss() where a CountDownLatch was counted down on an execution of the test source that got cancelled for a scale up event (despite its name, a scale up can happen in the test as well). This test instability only happens if there is enough time between the notification of new slots so that the source can start in between. On fast machines, the execution gets cancelled during scheduling, because the slots arrive together. With this commit, we are not using a latch, but counting the number of running instances explicitly. -- This is an automated message from the Apache Git Service.
