--------------------------------------

             Summary: Do not assume spark.submit.deployMode is always set
                 Key: SPARK-10711
                 URL: https://issues.apache.org/jira/browse/SPARK-10711
             Project: Spark
          Issue Type: Bug
          Components: R
    Affects Versions: 1.6.0
            Reporter: Hossein Falaki
            Priority: Critical


in RRDD.createRProcess() we call RUtils.sparkRPackagePath(), which assumes "... 
that Spark properties `spark.master` and `spark.submit.deployMode` are set."

It is better to assume safe defaults if they are not set.
