 * A lower-level, unstable API intended for developers.

 * Developer API's might change or be removed in minor versions of Spark.

 * NOTE: If there exists a Scaladoc comment that immediately precedes this
 * annotation, the first line of the comment must be ":: DeveloperApi ::" with
 * no trailing blank line. This is because of the known issue that Scaladoc
 * displays only either the annotation or the comment, whichever comes first.
