Question: if I understand the code correctly, SPARK_YARN_APP_NAME will
never be used (since I don't think it's possible to instantiate a SparkContext
without spark.app.name being set in the corresponding SparkConf).
If that's true, is there any point in keeping SPARK_YARN_APP_NAME around?
If there is, I'd have to switch the conditions around (so that it overrides the
value in SparkConf).
