----------------------------------------
Thank you [~BilwaST] for raising this
Issue looks like API interface level issue DominantResourceCalculator#compare
or wrong usage. *0* should be returned only when all the resources are equal.
But in this case if one resource is greater and other is less the the compare
returns *0*
{code:java}
/**
* Compare two resources - if the value for every resource type for the lhs
* is greater than that of the rhs, return 1. If the value for every resource
* type in the lhs is less than the rhs, return -1. Otherwise, return 0
*
* @param lhs resource to be compared
* @param rhs resource to be compared
* @return 0, 1, or -1
*/
private int compare(Resource lhs, Resource rhs) {
public int compare(Resource clusterResource, Resource lhs, Resource rhs,
boolean singleType) {
{code}
Cluster resource <10,10,0> memory,cpu,gpu
||lhs||rhs||
|<1,0>|<0,1>|returns --> 0|
ResourceCalculator#compare expects *0* only if values are equal.
All the callers that expects all the fields to be
lessthanEqual/greaterThanEqual are affected.
