> Key: HADOOP-19391
> URL: https://issues.apache.org/jira/browse/HADOOP-19391
> Project: Hadoop Common
> Issue Type: Improvement
> Components: tools
> Affects Versions: 3.4.1
> Reporter: farmmamba
> Assignee: farmmamba
> Priority: Minor
> Labels: pull-request-available
>
> Two points:
> # Use `Time.monotonicNow()` rather than `System.currentTimeMillis()` to calculate time consumption, because when we only test metadata performance, the resolution of `System.currentTimeMillis()` can not meet our needs.
> # The decription of NNBench's parameters are not clearly stated.
