I'm seeing lines like this (CDH 5.10.0)   2017-06-12 21:52:12,937 INFO org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.FairScheduler: Should preempt <memory:28672, vCores:-8> res for queue root.production.scheduled_jobs: resDueToMinShare = <memory:0, vCores:0>, resDueToFairShare = <memory:28672, vCores:-8>   Note the negative number for vCores.  Is this a manifestation of YARN-6175, which I see was not part of CDH 5.10.0?   Thanks, Aaron ...
