Zhe Zhang commented on HDFS-10534:
----------------------------------
Should this (adding a metric and adding it to web UI) be considered an
incompatible change? If not I'd like to backport to 2.6.
[~andrew.wang] [~vinodkv] Any advice? Thanks.

> In addition of *Min/Median/Max*, another meaningful metric for cluster
> balance is DN usage rate at a certain percentile (e.g. 90 or 95). We should
> add a config option, and another filed on NN WebUI, to display this.
