wangwj updated YARN-7859:
-------------------------
    Description: 
     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...

    Now the way of community solves queue scheduling to starvation is preempt container.But
this way may increases the failure rate of the job.
    On the basis of the above, I propose this issue...
