>          Issue Type: Improvement
>          Components: Distributed Coordination, State Backends, Checkpointing
>    Affects Versions: 1.2.0

>             Fix For: 1.2.0
> 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.
