> Currently, the autoscaler will scale a job when the JobStatus is RUNNING. But
> the JobStatus will be RUNNING once job starts schedule, so it doesn't mean
> all tasks are running. Especially, when the resource isn't enough or job
> recovers from large state.
> The autoscaler will throw exception and generate the AutoscalerError event
> when tasks are not ready, such as:
> !image-2024-03-21-17-40-23-523.png!
> Also, we don't need to scale it when some tasks are not ready.
> Solution: we only scale job that all tasks are running(some of tasks may be
> finished).
