Question
You have a cluster running with a FIFO scheduler enabled. You submit a large job A to the cluster, which you expect to run for one hour. Then, you submit job B to the cluster, which you expect to run a couple of minutes only. You submit both jobs with the same priority. Which two best describes how FIFO Scheduler arbitrates the cluster resources for job and its tasks?
Options
- ABecause there is a more than a single job on the cluster, the FIFO Scheduler will enforce a limit
- BTasks are scheduled on the order of their job submission
- CThe order of execution of job may vary
- DGiven job A and submitted in that order, all tasks from job A are guaranteed to finish before all
- EThe FIFO Scheduler will give, on average, and equal share of the cluster resources over the job
- FThe FIFO Scheduler will pass an exception back to the client when Job B is submitted, since all
