YAYA - YARN tutorial and API

Try and YARN in less then 5

This project has two main goals.

1. To serve as a tutorial for those who would like to learn YARN
2. An attempt to define a simpler (developer friendly) YARN API, that the end user can use. - Yet Another Yarn API (YAYA?)

YARN could and should be as simple as:

// Create a command to be executed in the container launched by the Application Master
UnixCommand applicationCommand = new UnixCommand("cal");
// or create a Java command
// JavaCommand applicationCommand = new JavaCommand(HelloWorld.class);

// Create YARN application
YarnApplication yarnApplication = 
          YarnApplicationBuilder.forApplication("sample-yarn-app", applicationCommand).build();

// Launch YARN application
yarnApplication.launch();
