>                 URL: https://issues.apache.org/jira/browse/SAMZA-2303
>             Project: Samza
>          Issue Type: Bug
>            Reporter: Cameron Lee
>            Priority: Major
>
> OperatorImplGraph builds EndOfStreamStates and WatermarkStates objects with all of the input SSPs from the job model. That includes side-input SSPs. However, high-level operator tasks aren't given messages from side-input SSPs, so high-level operators should not need to include handling for end-of-stream and watermarks.
> The result of this issue is that end-of-stream and watermark handling tries to include side-inputs but never updates those states, which can result in not exiting properly (end-of-stream) and not correctly calculating watermarks.
