[jira] [Created] (SPARK-2914) spark.*.extraJavaOptions are escaped too many times

Andrew Or created SPARK-2914:
--------------------------------

             Summary: spark.*.extraJavaOptions are escaped too many times
                 Key: SPARK-2914
                 URL: https://issues.apache.org/jira/browse/SPARK-2914
             Project: Spark
          Issue Type: Bug
          Components: Spark Core
    Affects Versions: 1.0.2
            Reporter: Andrew Or
             Fix For: 1.1.0


If we pass the following to spark.executor.extraJavaOptions,
{code}
-Dthem.quotes="the \"best\" joke ever" -Dthem.backslashes="\\ \\ \\\\"
{code}
These will first be escaped once when the SparkSubmit JVM is launched. This becomes the following string.
{code}
scala> sc.getConf.get("spark.driver.extraJavaOptions")
res0: String = -Dthem.quotes="the "best" joke ever" -Dthem.backslashes=" \ \ \\ "
{code}
This will be split incorrectly by Utils.splitCommandString.
