>      As everyone knows.In FairScheduler the phenomenon of queue scheduling starvation
often occurs when the number of cluster jobs is large.The App in one or more queue are pending.So
I have thought a way to solve this problem.Add queue scheduling deadLine in fairScheduler.When
a queue is not scheduled for FairScheduler within a specified time.We mandatory scheduler
it!
>     On the basis of the above, I propose this issue...
