-----------------------------------------
For some reason this hasn't been run through hudson, could you resubmit the patch Brian?

> Metrics averages are not averages; instead of updating the metric with the average number periodically, Hadoop metrics *increments* the metric.
> I.e., each update we have value = old_value + current average. Instead, we want each update to have value = current_average.
> Patch will be attached momentarily.
