Hadoop mapreduce : Driver for chaining mappers within a MapReduce job

I have mapreduce job: my code Map class:

public static class MapClass extends Mapper<Text, Text, Text, LongWritable> {

    @Override
    public void map(Text key, Text value, Context context)
        throws IOException, InterruptedException {
    }
}

And I want to use ChainMapper :

1. Job job = new Job(conf, "Job with chained tasks");
2. job.setJarByClass(MapReduce.class);
3. job.setInputFormatClass(TextInputFormat.class);
4. job.setOutputFormatClass(TextOutputFormat.class);

5. FileInputFormat.setInputPaths(job, new Path(InputFile));
6. FileOutputFormat.setOutputPath(job, new Path(OutputFile));

7. JobConf map1 = new JobConf(false);

8. ChainMapper.addMapper(
        job, 
        MapClass.class, 
        Text.class, 
        Text.class, 
        Text.class, 
        Text.class, 
        true, 
        map1
        ); 

but its report has an error at line 8 :

Multiple markers at this line - Occurrence of 'addMapper' - The method addMapper(JobConf, Class>, Class, Class, Class, Class, boolean, JobConf) in the type ChainMapper is not applicable for the arguments (Job, Class, Class, Class, Class, Class, boolean, Configuration) - Debug Current Instruction Pointer - The method addMapper(JobConf, Class>, Class, Class, Class, Class, boolean, JobConf) in the type ChainMapper is not applicable for the arguments (JobConf, Class, Class, Class, Class, Class, boolean, JobConf)
