> Metrics2 has a whole bunch of race conditions and weird edges because of all 
> of the caching that metrics2 does.
> Additionally tying something so integral to hadoop who has lots of versions 
> we support has been a maintenance nightmare. It would allow us to completely 
> get rid of the compat modules.
> Rip it out.
