>
> 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,
> https://issues.apache.org/jira/browse/APEXMALHAR-2422
