Your cluster is running MapReduce version 2 (MRv2) on YARN. Your ResourceManager is
configured to use the FairScheduler. Now you want to configure your scheduler such that a
new user on the cluster can submit jobs into their own queue application submission. Which
configuration should you set?

A.
You can specify new queue name when user submits a job and new queue can be
created dynamically if the property yarn.scheduler.fair.allow-undecleared-pools = true

B.
You can specify new queue name per application in allocations.xml file and have new
jobs automatically assigned to the application queue

C.
Yarn.scheduler.fair.user.fair-as-default-queue = false and
yarn.scheduler.fair.allowundecleared-pools = true

D.
You can specify new queue name when user submits a job and new queue can be
created dynamically if yarn .schedule.fair.user-as-default-queue = false
