Arpit Agarwal commented on HDFS-7483:
-------------------------------------

Hi [~benoyantony], thanks for this improvement. This would be great to have.

Do you think it makes sense to add the Storage Types table to the overview 
page? It is hidden in the utilities tab. Also we can make the table sortable on 
individual columns in another Jira.

These parameters look unused:
{code}
+      float percentUsed, float percentRemaining) {
{code}

I also agree with the suggestion of letting the client calculate the 
percentages. Not commenting on the html/js changes since Haohui has given 
feedback and he is way more familiar.
