------------------------------------

No other js code has unit tests so I'm fine going ahead with this.

I'll commit today if nobody has any concern.

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.
