> In case of leaf queue the AM resource calculation is based on {{absoluteCapacityResource}}. Below is the calculation for absolute capacity
> {{LeafQueue#updateAbsoluteCapacityResource()}}
> {code}
> private void updateAbsoluteCapacityResource(Resource clusterResource) {
> absoluteCapacityResource =
> Resources.multiplyAndNormalizeUp(resourceCalculator, labelManager
> .getResourceByLabel(RMNodeLabelsManager.NO_LABEL, clusterResource),
> queueCapacities.getAbsoluteCapacity(), minimumAllocation);
> }
> {code}
> If default partition resource is zero for all Leaf queue the resource for AM will be zero
> Snapshot also attached for the same
