      Description

      When a job finishes, there may be some zombie tasks still running due to stage retry. Since a result stage will never be used by other jobs, running these tasks are just wasting the cluster resource. This PR just asks TaskScheduler to cancel the running tasks of a result stage when it's already finished. Credits go to @srinathshankar who suggested this idea to me.
