----------------------------------
Assignee: (was: Cameron Lee)
> Exclude side inputs when handling end-of-stream and watermarks for high-level
> -----------------------------------------------------------------------------
>
> Key: SAMZA-2303
> 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.
