* vi log4j.properties
 在生產環境下 應該使用error 模式，能打打減小 空間消耗
       >log4j.rootCategory=INFO, console 
 	   改成
 	   log4j.rootCategory=ERROR, console
 * vi slaves
  加上其它節點hostname 
 * vi spark-defaults.conf 
       >spark.serialize                                  org.apache.spark.serializer.KryoSerializer 取消其註釋
 * 製做job啓動腳本 **可選操做**  只適用於如今的job 結構
