First stab at adding JobTracker/TaskTracker support. This is failing chefspec and I am not sure why. The package is available on CentOS 6.4 using hadoop['distribution'] == 'cdh' in Vagrant.
Output cleanup
Use node.override to set hadoop['distribution'] to 'cdh'... thanks to @sethvargo for helping me out in sethvargo/chefspec#432
Remove unused code
Move TODO documentation to JobTracker
Adding status_command to services
Merge branch 'master' into feature/jobtracker-support
