Hi, do you mean "getOrElse(MRJobConfig.DEFAULT_MAPREDUCE_APPLICATION_CLASSPATH)" ? I have a compilation error here, saying that StringUtils.getStrings requires a String but gets a Array[String]. And in hadoop CDH 4.6, we have

  public static final String[] DEFAULT_MAPREDUCE_APPLICATION_CLASSPATH = {
      "$HADOOP_MAPRED_HOME/share/hadoop/mapreduce/*",
      "$HADOOP_MAPRED_HOME/share/hadoop/mapreduce/lib/*",
  };
