sandflee commented on YARN-5254:
--------------------------------
vcore info is droped by DefaultResourceCalculator while normalize resource
request in allocate() , we can:
1, change DefaultResourceCalculator#normalize()
2, use DefaultResourceCalculator to normalize resource request like
fairscheduler
use 2, and update a patch
> capacity scheduler could only allocate a container with 1 vcore if using
> DefautResourceCalculator
