> 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.
