Varun Vasudev commented on YARN-5254:
-------------------------------------
[~sandflee] - the behaviour to ignore vcores in DefaultResourceCalculator is by
design. If you wish to take vcores into account with CapacityScheduler, you can
change the calculator in capacity-scheduler.xml by setting
yarn.scheduler.capacity.resource-calculator to
org.apache.hadoop.yarn.util.resource.DominantResourceCalculator.
> capacity scheduler could only allocate a container with 1 vcore if using
> DefautResourceCalculator
