问题描述

本地eclipse运行 hadoop-2.6 mapreduce 报错，求助

报错信息是：

解决方案

没人回答，我搞好了，自己说下原因吧
其实就是配置的文件路径不对，
修改设置文件路径的代码：
String[] ioArgs=new String[]{"hdfs://192.168.10.231:9000/user/fire/dedup_in","hdfs://192.168.10.231:9000/user/fire/dedup_out"};
//设置输入和输出目录
FileInputFormat.addInputPath(job, new Path(otherArgs[0]));

    FileOutputFormat.setOutputPath(job, new Path(otherArgs[1]));
