> Project: Flink
> Issue Type: Bug
> Components: Runtime / Checkpointing
> Affects Versions: 0.10.0
> Reporter: Robert Metzger
> Priority: Critical

> While implementing a test case for the Kafka Consumer, I came across the
> following bug:
> Consider the following topology, with the operator parallelism in parentheses:
> Source (2) --> Sink (1).
> In this setup, the {{snapshotState()}} method is called on the source, but
> not on the Sink.
> The sink receives the generated data.
> only one of the two sources is generating data.
> I've implemented a test case for this, you can find it here:
