on the cluster, and you submit a job A, so that only job A is running on the cluster. A while
later, you submit Job B. now Job A and Job B are running on the cluster at the same time.
How will the Fair Scheduler handle these two jobs? (Choose 2)

fewer tasks.
B. When Job B gets submitted, Job A has to finish first, before job B can gets scheduled.
