[jira] [Created] (REEF-35) Include vCore-checking in the YARN Container matching algorithm

John Yang created REEF-35:
-----------------------------

             Summary: Include vCore-checking in the YARN Container matching algorithm
                 Key: REEF-35
                 URL: https://issues.apache.org/jira/browse/REEF-35
             Project: REEF
          Issue Type: Bug
            Reporter: John Yang
            Assignee: John Yang


This issue has been discovered while working on REEF-6.

As a workaround for YARN-2380, the part that examines vCores was removed from the matching algorithm

But this can result in allocating less vCores than requested. This happens when not using the default CapacityScheduler and also when certain race conditions are met.

Once YARN-2380 is resolved, we should be able to do vCore matching again.
