Assignee: Shanmukha Haripriya Kota
> Metrics recording a time duration should use System.nanoTime()

> Key: HBASE-25150

> Project: HBase
> Issue Type: Bug
> Components: metrics
> Reporter: Nick Dimiduk
> Assignee: Shanmukha Haripriya Kota
> Priority: Major
>
> I was looking around in our table metrics and noticed that scan time is
> collected using {{EnvironmentEdgeManager.currentTime()}}. This isn't a stable
> way to measure a duration of time on the jvm. We should convert all these
> occurrences to use {{TimeUnit.NANOSECONDS.toMillis(System.nanoTime())}}
> instead.
