    Description

      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);
  }
