------------------------------------
Status: Open (was: Patch Available)
> Metric Averages are not averages
> --------------------------------
>
> Key: HADOOP-4369
> URL: https://issues.apache.org/jira/browse/HADOOP-4369
> Project: Hadoop Core
> Issue Type: Bug
> Components: metrics
> Affects Versions: 0.18.1
> Reporter: Brian Bockelman
> Fix For: 0.18.2
>
> Attachments: hadoop-4369.patch
>
> Original Estimate: 0.17h
> Remaining Estimate: 0.17h

> 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.
