The job submission code can be written this way.
// Create a new Job
Job job = new Job(new Configuration());
job.setJarByClass(MyJob.class);
// Specify various job-specific parameters
job.setJobName("myjob");
job.setInputPath(new Path("in"));
job.setOutputPath(new Path("out"));
job.setMapperClass(MyJob.MyMapper.class);
job.setReducerClass(MyJob.MyReducer.class);
// Submit the job
job.submit();
For submitting this, need to add the hadoop jar files and configuration
files in the class path of the application from where you want to
submit the job.
You can refer this docs for more info on Job API's.
