Could you add a helper method for this instead? You could have something like: def loadPropertiesFile(file: Option[String], conf: SparkConf): Map[String, String] = { val path = file.getOrElse(getDefaultConfigFile())) getPropertiesFromFile(file) .filter { case (k, v) => k.startsWith("spark.") } .foreach { case (k, v) => conf.setIfMissing(k, v) sys.props.getOrElseUpdate(k, v) } } And this whole block becomes a single method call. If you're creative you could even come up with an API that could be used by the SparkSubmit code too.
