我为hadoop流运行以下命令

hadoop jar contrib/streaming/hadoop-streaming-1.0.3.jar -input test1/testregxml.xml -output testoutput2 -file ~/Programs/CMapper.php -mapper ~/Programs/CMapper.php -jobconf mapred.reduce.tasks=1

hadoop任务失败，输出如下

12/10/26 15:36:56 WARN streaming.StreamJob: -jobconf option is deprecated, please use -

D instead.
