从远程系统提交mapreduce作业时出现异常
13/10/28 18:49:52错误security.usergroupinformation:priviledgedactionexception as:rootcause:org.apache.hadoop.mapred.invalidinputexception：输入路径不存在：file:/f:/workspaces/test/hadoop/test
我的hadoop和mapreduce环境是在linux机器上配置的。我从本地windows pc提交wordcount作业，如下所示：

public static void main(String[] args) throws Exception {

    UserGroupInformation ugi = UserGroupInformation.createRemoteUser("root");

    try {
        ugi.doAs(new PrivilegedExceptionAction<Void>() {

            public Void run() throws Exception {

                JobConf conf = new JobConf(MapReduce.class);
                conf.set("mapred.job.name", "MyApp");
                conf.set("mapred.job.tracker", "192.168.1.149:9001");
                conf.set("fs.default.name","hdfs://192.168.1.149:9000");
                conf.set("hadoop.job.ugi", "root");

                conf.setOutputKeyClass(Text.class);
                conf.setOutputValueClass(IntWritable.class);

                conf.setMapperClass(Map.class);
                conf.setCombinerClass(Reduce.class);
                conf.setReducerClass(Reduce.class);

                conf.setInputFormat(TextInputFormat.class);
                conf.setOutputFormat(TextOutputFormat.class);

                FileInputFormat.setInputPaths(conf, new Path("test"));
                FileOutputFormat.setOutputPath(conf, new Path("test"));

                JobClient.runJob(conf);

                return null;
            }
        });
    } catch (Exception e) {
        e.printStackTrace();
    }
}

其中192.168.1.149是hadoop配置的linux pc。我在那里启动了hadoop、mapreduce服务。测试目录也是用同样的javaapi创建的，它工作正常。但mapreduce不是。

请帮忙
