Attachment: (was: HADOOP-14713.01.patch)
> Audit for durations that should be measured via Time.monotonicNow
> -----------------------------------------------------------------

> Key: HADOOP-14713
> URL: https://issues.apache.org/jira/browse/HADOOP-14713
> Project: Hadoop Common
> Issue Type: Improvement
> Reporter: Jason Lowe
> Labels: newbie
>
> Whenever we are measuring a time delta or duration in the same process, the
> timestamps probably should be using Time.monotonicNow rather than Time.now or
> System.currentTimeMillis. The latter two are directly reading the system
> clock which can move faster or slower than actual time if the system is
> undergoing a time adjustment (e.g.: adjtime or admin sets a new system time).
> We should go through the code base and identify places where the code is
> using the system clock but really should be using monotonic time.
