@zjureel Thanks for this patch. I will pick it up from here.
I think there is a small additional change needed, and a test, but I can do
that...
> Pass a callback type to the RestartStrategy, rather than the full
> ExecutionGraph

> Key: FLINK-6667
> URL: https://issues.apache.org/jira/browse/FLINK-6667
> Project: Flink
> Issue Type: Sub-task
> Components: Distributed Coordination
> Affects Versions: 1.3.0
> Reporter: Stephan Ewen
> Assignee: Fang Yong
>
> To let the {{ResourceStrategy}} work across multiple {{FailoverStrategy}}
> implementations, it needs to be passed a "callback" to call to trigger the
> restart of tasks/regions/etc.
> Such a "callback" would be a nice abstraction to use for global restarts as
> well, to not expose the full execution graph.
> Ideally, the callback is one-shot, so it cannot accidentally be used to call
> restart() multiple times.
> This would also make the testing of RestartStrategies much easier.
