[jira] [Commented] (OOZIE-1817) Oozie timers are not biased

["Robert Kanter (JIRA)" <ji...@apache.org>]

Robert Kanter commented on OOZIE-1817:
--------------------------------------

I think for this we should transition to the Codahale Metrics library; it also provides a bunch of other useful things that we could maybe take advantage of.  The API looks pretty similar to what we're already using, so switch to it shouldn't be too hard.

Of course, for compatibility, we'll keep the current Instrumentation, but eventually we could get remove of it.

> 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).
