Summary: Resourcemanager hangs when
resourceUsedWithWeightToResourceRatio return a overflow value
Key: YARN-7560

Project: Hadoop YARN
Issue Type: Bug
Components: resourcemanager
Affects Versions: 2.7.1, 3.0.0

When we debug the cluster, we found resourceUsedWithWeightToResourceRatio
return a negative value. So the loop can't return. We found in our cluster, all
minRes is over int.max.
