> Since we have put all non-IO operations of {{CheckpointCoordinator}} into
> main thread executor, the {{CheckpointFailureManager.FailJobCallback}} could
> be executed directly now. In this way execution graph would fail immediately
> when {{CheckpointFailureManager}} invokes the callback. We could avoid the
> inconsistent scenario of FLINK-13497.
