/**
 * 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.
 * 

 * Divided into a main program ({@link DrillOnYarn}) and a series of commands.
 * Some commands are further divided into tasks. Builds on the
 * YARN and DFS facades defined in the core module.
