Andrew Or commented on SPARK-2914:
----------------------------------
https://github.com/apache/spark/pull/1845
> spark.*.extraJavaOptions are evaluated 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.
> Of course, this also affects spark.driver.extraJavaOptions.
