             Summary: Spark query available cores from application
                 Key: SPARK-19782
                 URL: https://issues.apache.org/jira/browse/SPARK-19782
             Project: Spark
          Issue Type: New Feature
          Components: Spark Core
    Affects Versions: 2.1.0
            Reporter: Tom Lewis


It might be helpful for Spark jobs to self regulate resources if they could 
query how many cores exist on a executing system not just how many are being 
used at a given time.
