>
> {{LazyFromSourcesSchedulingStrategy}} now will only schedule tasks in CREATED state. 
> However, the DefaultScheduler will reset failed tasks when actually restarting them.
> This makes failed tasks not able to be restarted with {{LazyFromSourcesSchedulingStrategy}}.
> We can keep {{LazyFromSourcesSchedulingStrategy}} to schedule tasks in CREATED state in normal scheduling. And make it schedule tasks in terminal state when trying to restart tasks.
> This issue also fails some IT cases on DefaultScheduler, e.g. JobRecoveryITCase.
