> The KafkaSinglePortExactlyOnceOutputOperator fails on recovery with the
> message: "Violates Exactly once. Not all the tuples received after operator
> reset."
> This is because of this check in endWindow():
> {code}
> if (!partialWindowTuples.isEmpty() && windowId >
> windowDataManager.getLargestCompletedWindow()) {
> throw new RuntimeException("Violates Exactly once. Not all the tuples
> received after operator reset.");
> }
> {code}
