Yes, we should update all subclasses with the one-argument constructor. If
the `AbstractInvokable` does not have a zero-argument constructor any more, all
subclasses will be forced to call the one-argument constructor.
> Set task state to RUNNING after state has been restored

> URL: https://issues.apache.org/jira/browse/FLINK-4714
> Project: Flink
> Issue Type: Improvement
> Components: Distributed Coordination, State Backends, Checkpointing
> Affects Versions: 1.2.0
> Reporter: Till Rohrmann
> Assignee: Wei-Che Wei
>
> 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.
