Date Thu, 07 Jul 2016 23:00:15 GMT

    [ https://issues.apache.org/jira/browse/HDFS-10534?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15366927#comment-15366927

Zhe Zhang commented on HDFS-10534:

Thanks [~lewuathe]! Screenshot looks very nice.

On the first glance the js file added in the patch is very large. Is it necessary? I haven't
actually applied and reviewed it, just a quick comment.

> In addition of *Min/Median/Max*, another meaningful metric for cluster balance is DN
usage in histogram style.
> Since NN already has provided necessary information to calculate histogram of DN usage,
it can be done in JS side.
