> 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!
> 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...
