I don't know how to test the js easily. As [~elgoiri] said, it is better to
provide some unit tests. So could you review the patch and give some comments?

> Key: HDFS-13844
> URL: https://issues.apache.org/jira/browse/HDFS-13844
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: hdfs, ui
> Affects Versions: 1.2.0, 2.2.0, 2.7.2, 3.0.0, 3.1.0
> Reporter: yanghuafeng
> Assignee: yanghuafeng
> Priority: Minor
> Attachments: HDFS-13844.001.patch, overflow_undefined_unit.jpg,
> overflow_unit.jpg, undefined_unit.jpg
>
>
> The namenode WebUI cannot display the capacity with correct units. I have
> found that the function fmt_bytes in the dfs-dust.js missed the EB unit. This
> will lead to undefined unit in the ui.
> And although the unit ZB is very large, we should take the unit overflow into
> consideration. Supposing the last unit is GB, we should get the 8192 GB with
> the total capacity 8T rather than 8 undefined.
