Description

In case of leaf queue the AM resource calculation is based on absoluteCapacityResource. Below is the calculation for absolute capacity

LeafQueue#updateAbsoluteCapacityResource()

  private void updateAbsoluteCapacityResource(Resource clusterResource) {
    absoluteCapacityResource =
        Resources.multiplyAndNormalizeUp(resourceCalculator, labelManager
            .getResourceByLabel(RMNodeLabelsManager.NO_LABEL, clusterResource),
            queueCapacities.getAbsoluteCapacity(), minimumAllocation);
  }

If default partition resource is zero for all Leaf queue the resource for AM will be zero
