(was: Enable testing of different re-scaling scenarios in the
AbstractStreamOperatorTestHarness )
> Allow the AbstractStreamOperatorTestHarness to test scaling down

> Key: FLINK-4960
> URL: https://issues.apache.org/jira/browse/FLINK-4960
> Project: Flink
> Issue Type: New Feature
> Components: Tests
> Reporter: Kostas Kloudas
> Assignee: Kostas Kloudas
> Fix For: 1.2.0
>
>
> Currently the AbstractStreamOperatorTestHarness allows for testing scaling
> up scenarios through snapshot and restore. This is not enough to check
> scaling down scenarios or different combinations of up and down.
> This issue targets to add this functionality so that an operator can snapshot
> its state, restore with different parallelism, and later scale down or
> further up.
