John George commented on HDFS-8291:
-----------------------------------
[~benoyantony] Good point - I agree that TB is more widely used. It makes sense
that we change the calculation to display the units as TB.
As an added credit, [~zhongyi-altiscale] if you can display 1TB=10 ^12^ bytes
on the NN Web UI that would be great as well.
> Modify NN WebUI to display correct unit

> NN Web UI displays its capacity and usage in TB, but it is actually TiB. We
> should either change the unit name or the calculation to ensure it follows
> standards.
