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

Hi Andrew, are you still working on the task? If not, I can also work on it, because the task I want to work on is blocked by this issue.

> The task state is set to {{RUNNING}} as soon as the {{Task}} is executed. That, however, happens before the state of the {{StreamTask}} invokable has been restored. As a result, the {{CheckpointCoordinator}} starts to trigger checkpoints even though the {{StreamTask}} is not ready.
> In order to avoid aborting checkpoints and properly start it, we should switch the task state to {{RUNNING}} after the state has been restored.
