> Project: Flink
> Issue Type: Bug
> Components: DataStream API
>Affects Versions: 1.2.1, 1.4.0, 1.3.2
>Reporter: Tzu-Li (Gordon) Tai

>
> Currently, once all inputs of a {{StatusWatermarkValve}} becomes idle, we
> only emit the {{StreamStatus.IDLE}} marker, and check nothing else. This
> makes the watermark advancement behavior inconsistent in the case that all
> inputs become idle, depending on the order that they become idle.
> Consider the following setup:
> {code}
> Channel #1: Watermark 10, ACTIVE
> Channel #2: Watermark 5, ACTIVE
> Channel #3: Watermark 5, ACTIVE
> {code}
> If the channels become IDLE with the order #2 -> #3 -> #1, watermark 10 will
> be emitted as the new min watermark once both #2 and #3 becomes idle.
> On the other hand, if the order is #1 -> #2 -> #3, watermark 10 will not be
> emitted.
