> Issue Type: Bug
> Reporter: Munagala V. Ramanath
> Assignee: Sandesh

> 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}
> Note:
> It is failing because of the bug in the WindowDataManager,
