             Summary: No way to dynamically set env vars on driver in cluster 
mode
                 Key: SPARK-16194
                 URL: https://issues.apache.org/jira/browse/SPARK-16194
             Project: Spark
          Issue Type: Bug
    Affects Versions: 2.0.0
            Reporter: Michael Gummelt


I often need to dynamically configure a driver when submitting in cluster mode, 
but there's currently no way of setting env vars.  {{spark-env.sh}} lets me set 
env vars, but I have to statically build that into my spark distribution.  I 
need a solution for specifying them in {{spark-submit}}.  Much like 
{{spark.executorEnv.[ENV]}}, but for drivers.
