> This issue happens after YARN-8720.
> Before that, AMS uses scheduler.getMaximumAllocation to do the normalization.
> After that, AMS uses LeafQueue.getMaximumAllocation. The scheduler one uses
> nodeTracker.getMaximumAllocation, but the LeafQueue.getMaximum doesn't.
> We should use the scheduler.getMaximumAllocation to cap the per-queue's
> maximum-allocation every time.
