> The value of *demand* of leaf queue that we now view on the fair scheduler page shows only the value of *maxResources* when the demand value is greater than *maxResources*. It doesn't reflect the real situation. Most of the time, when we expand the queue, we often rely on seeing the current demand real value.

> private void updateDemandForApp(FSAppAttempt sched, Resource maxRes) {
>     sched.updateDemand();
>     Resource toAdd = sched.getDemand();
>     if (LOG.isDebugEnabled()) {
>       LOG.debug("Counting resource from " + sched.getName() + " " + toAdd
>           + "; Total resource consumption for " + getName() + " now "
>           + demand);
>     }
>     demand = Resources.add(demand, toAdd);
>     demand = Resources.componentwiseMin(demand, maxRes);
>   }
> {code}
