Package org.apache.drill.yarn.client

package org.apache.drill.yarn.client
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 (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.
