Github user StephanEwen commented on the issue: https://github.com/apache/flink/pull/2588 Looks good, thanks, will merge this. I would suggest two followups: - We can remove the "dispose savepoint" method, because that is functionality disappearing right now. Savepoints need no special remove logic any more, they are just a directory in a filesystem. - We can reduce the number of message classes (like `TriggerSavepointResponse`) by using exceptions more prominently. The "triggerSavepoint()" method could simply return a String (success) or throw an exception (failure). Exceptions are propagated by the RPC, so the caller future will always get it as a response.
