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?
A.
Because there is a more than a single job on the cluster, the FIFO Scheduler will enforce a limit
on the percentage of resources allocated to a particular job at any given time
B.
Tasks are scheduled on the order of their job submission
C.
The order of execution of job may vary
D.
Given job A and submitted in that order, all tasks from job A are guaranteed to finish before all
tasks from job B
E.
The FIFO Scheduler will give, on average, and equal share of the cluster resources over the job
lifecycle
F.
The FIFO Scheduler will pass an exception back to the client when Job B is submitted, since all
slots on the cluster are use
