Zian Chen commented on YARN-8004:
---------------------------------
Hi [~eepayne] , Please allow me to explain here a little bit. The tests which
extends ProportionalCapacityPreemptionPolicyMockFramework were not use
DefaultResourceCalculator by default. There is a config to enable/disable DRF
in the Unit test which is the last parameter in method buildEnv. The related
code is below,
{code:java}
// code placeholder
public void buildEnv(String labelsConfig, String nodesConfig,
String queuesConfig, String appsConfig,
boolean useDominantResourceCalculator) throws IOException {
if (useDominantResourceCalculator) {
when(cs.getResourceCalculator()).thenReturn(
new DominantResourceCalculator());
}
{code}
So when we set the last parameter to true, we will use DRF calculator.
> Add unit tests for inter queue preemption for dominant resource calculator
