> There are a few confusing places in the [Hadoop Metrics
> page|https://hadoop.apache.org/docs/stable/hadoop-project-dist/hadoop-common/Metrics.html].
> For instance, there are duplicated entries such as {{FsImageLoadTime}}; some
> quantile metrics do not have corresponding entries, description on some
> quantile metrics are not very specific on what is the {{num}} variable in the
> metrics name, etc.
> This JIRA targets at improving this.
