[jira] [Updated] (HDFS-16595) Slow peer metrics - add median, mad and upper latency limits

     [ https://issues.apache.org/jira/browse/HDFS-16595?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Viraj Jasani updated HDFS-16595:
--------------------------------
    Release Note: Namenode metrics that represent Slownode Json now include three important factors (median, median absolute deviation, upper latency limit) that can help user determine how urgently a given slownode requires manual intervention.

> Slow datanode metrics include slow node and it's reporting node details. With HDFS-16582, we added the aggregate latency that is perceived by the reporting nodes.
> In order to get more insights into how the outlier slownode's latencies differ from the rest of the nodes, we should also expose median, median absolute deviation and the calculated upper latency limit details.
