| <div class="block"><p>Superclass of many Mahout Hadoop "jobs". A job drives configuration and launch of one or |

| |
| <p>Command line arguments available to all subclasses are:</p> |
| |
| <ul> |
| <li>--tempDir (path): Specifies a directory where the job may place temp files |
| (default "temp")</li> |
| <li>--help: Show help message</li> |
| </ul> |
| |
| <p>In addition, note some key command line parameters that are parsed by Hadoop, which jobs |
| may need to set:</p> |
| |
| <ul> |
| <li>-Dmapred.job.name=(name): Sets the Hadoop task names. It will be suffixed by |
| the mapper and reducer class names</li> |
| <li>-Dmapred.output.compress={true,false}: Compress final output (default true)</li> |
| <li>-Dmapred.input.dir=(path): input file, or directory containing input files (required)</li> |
| <li>-Dmapred.output.dir=(path): path to write output files (required)</li> |
| </ul> |
| |
| <p>Note that because of how Hadoop parses arguments, all "-D" arguments must appear before all other |
| arguments.</p></div> |
