>             Project: Hadoop HDFS
>          Issue Type: Bug
>          Components: hdfs, ui
>    Affects Versions: 3.1.0, 3.0.0, 2.7.2, 2.2.0, 1.2.0
>            Reporter: yanghuafeng

> 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.
