Íñigo Goiri commented on HDFS-13059:
------------------------------------
[~aw], in the article you point, it mentions:
bq. The one single thing pie charts are good at is when you're comparing 2-3
different data points with very different amounts of information.
Is that our case here? I think so.

> 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.
