> Project: Flink
> Issue Type: Sub-task
> Components: Distributed Coordination
> Affects Versions: 1.7.0
> Reporter: Till Rohrmann

> Priority: Major
> Fix For: 1.7.0
>
>
> Instead of simply calling into the {{RestartStrategy}} which restarts the
> existing {{ExecutionGraph}} with the same parallelism, the
> {{ExecutionGraphDriver}} should treat a recovery similar to the initial
> scheduling operation. First, one needs to decide on the new parallelism of
> the {{ExecutionGraph}} (scale up/scale down) wrt to the available set of
> resources. Only if the minimum configuration is fulfilled, the potentially
> rescaled {{ExecutionGraph}} will be restarted.
