> Oozie timers are not biased, that is, the statistical metrics they expose are
> over the run-time of the Oozie server instead of a window of time. This makes
> them not very useful especially after the server has been running for a while
> (codehale has very efficient and easy to use biased histograms that can be
> used instead).
