-------------------------------------

Hi [~till.rohrmann], have you started working on this? I would love to take this after the decoupling of ExecutionGraph in JobMaster.

> In order to scale down when there are not enough resources available or if TMs died, the {{ExecutionGraphDriver}} needs to learn about a failure. Depending on the failure type and the available set of resources, it can then decide to scale the job down or simply restart. In the scope of this issue, the {{ExecutionGraphDriver}} should simply call into the {{RestartStrategy}}.
