Summary: Improve documentation on Metrics
Key: HDFS-13674
URL: https://issues.apache.org/jira/browse/HDFS-13674
Project: Hadoop HDFS
Issue Type: Improvement
Components: documentation, metrics
Reporter: Chao Sun
Assignee: Chao Sun
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.
