Íñigo Goiri commented on HDFS-13059:
------------------------------------
To give a little bit more context, one of the reasons why I asked for the
refactor of the visualization functions is because I'd like to use them in
Router-based federation.
Actually, this goes into the point that [~aw] asked about how to compare
multiple clusters.
Currently, in RBF we have the following:
!fed-capacity.png!
This is a good starting point but there is no way to compare the sizes across
subclusters.
I'd like to use the pie chart or the histogram to show the space across
subclusters too.

> This jira proposes to add a pie chart in NN UI to show storage used by:
> * DFS Used (Tooltip : "Storage currently used for DFS.")
> * DFS available (Tooltip : "Storage available for DFS use.")
> * Non DFS Used (Tooltip : "Storage allocated for DFS but currently" +
> " used by Non DFS storage.")
> Tooltip will help users better understand what these terms mean.
