------------------------------------
I think it's important to check that the resources meet the minimum resource
allocation
{code:java}
// ParentQueue.java
@Override
public synchronized CSAssignment assignContainers(Resource clusterResource,
FiCaSchedulerNode node, ResourceLimits resourceLimits) {
CSAssignment assignment =
new CSAssignment(Resources.createResource(0, 0), NodeType.NODE_LOCAL);
Set<String> nodeLabels = node.getLabels();
if (!Resources.fitsIn(minimumAllocation, node.getAvailableResource())) {
return assignment;
}
...
}
{code}
> The capacity scheduler uses label to cause vcore to be incorrect
