Another solution if the interface cant be changed is to just convert to float
as following.Since value anyways converted to long the conversion to float
also will be fine.
{code}
@Override
public Resource multiplyAndNormalizeUp(Resource r, double by,
Resource stepFactor) {
return Resources.createResource(
roundUp(
(long) Math.ceil((float) (r.getMemorySize() * by)),
stepFactor.getMemorySize()),
roundUp(
(int) Math.ceil((float) (r.getVirtualCores() * by)),
stepFactor.getVirtualCores())
);
}
{code}

> Steps to reproduce
> ------------------------
> Setup cluster with 40 GB and 40 vcores with 4 Node managers with 10 GB each.
> Configure 100% to default queue as capacity and max am limit as 10 %
> Minimum scheduler memory and vcore as 512,1
> *Expected*
> AM limit 4096 and 4 vores
> *Actual*
> AM limit 4096+512 and 4+1 vcore
