Exception sending a mapreduce job from a remote system

Question

I got an exception when sending a mapreduce job from a remote system

10/13/28 6:49:52 PM ERROR security.UserGroupInformation: PriviledgedActionException as: root cause: org.apache.hadoop.mapred.InvalidInputException: input path does not exist: file: / F: / Workspaces / Test / Hadoop / test

My hadoop and mapreduce envirnment are configured on a Linux machine. I am sending a wordcount job from a local Windows PC as follows:

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();
    }
}

where 192.168.1.149 is the configured linux pc. I started using the services of on-line, mapreduce. A test directory was created with the same Java API. But mapreduce is not.

** Please, help.. **
