将路由：
Configuration conf = new Configuration();
conf.set("mapred.job.tracker", "10.2.173.15:9001");
String[] ioArgs = new String[] { "/user/guest/0Data", "/user/guest/0data" };
改写为：
FileInputFormat.addInputPath(job,new Path("hdfs://10.2.173.15:9000/user/guest/0Data"));
FileOutputFormat.setOutputPath(job, new Path("hdfs://10.2.173.15:9000/user/guest/0data"));
