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 peer metrics - add median, mad and upper latency limits

> 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.
