> Spark has two functions to kill all tasks in a Stage:
> * `cancelTasks`: Not only kill all the running tasks in all the stage 
> attempts but also abort all the stage attempts
> *  `killAllTaskAttempts`: Only kill all the running tasks in all the stage 
> attemtps but won't abort the attempts.
> However, there's no use case in Spark that a stage would launch new tasks 
> after its all tasks get killed. So I think we can replace 
> `killAllTaskAttempts` with `cancelTasks` directly.
