| <div class="block">Implements a "YARN client" for Drill-on-YARN. The client uploads files to |
| DFS, then requests that YARN start the Application Master. Much fiddling |
| about is required to support this, such as zipping up the user's configuration, |
| creating a local file with the app id so we can get app status and shut down |
| the app, etc. |
| <p> |
| Divided into a main program (<code>DrillOnYarn</code>) and a series of commands. |
| Some commands are further divided into tasks. Builds on the |
| YARN and DFS facades defined in the core module.</div> |
