| |
| <p>Here is an example on how to submit a job:</p> |
| <p><blockquote><pre> |
| // Create a new Job |
| Job job = Job.getInstance(); |
| job.setJarByClass(MyJob.class); |
| |
| // Specify various job-specific parameters |
| job.setJobName("myjob"); |

| |
| job.setMapperClass(MyJob.MyMapper.class); |
| job.setReducerClass(MyJob.MyReducer.class); |
| |
| // Submit the job, then poll for progress until the job is complete |
