> In the Capacity scheduler if you configure the queues to be hierarchical
> where you have root -> parent queue -> leaf queue, the leaf queue doesn't
> take into account its parents maximum capacity when calculate its own maximum
> capacity, instead it seems to use the parents capacity. Looking at the code
> its using the parents absoluteCapacity and I think it should be using the
> parents absoluteMaximumCapacity.
> It also seems to only use the parents capacity in the leaf queues max
> capacity calculation when the leaf queue has a max capacity configured. If
> the leaf queues maximum-capacity is not configured, then it can use 100% of
> the cluster.
