Matteo Bertozzi commented on HBASE-14986:
-----------------------------------------
I think the number needs to be "cleaned up" a bit.
to me, It will be useful to have a quick look at regions and see that "key
space of region2 is 5 times larger than the other regions".
> Display the key range for each region in the Regionserver UI

> The regionserver UI shows the start and end keys for each region, but it is
> hard for users to deduce the byte range between these.
> Unbalanced ranges can potentially lead to hot spots. Giving users an easy
> way to view the key range for each region and how these ranges compare across
> regions may help alleviate this problem.
> Key ranges may become non-uniform as a consequence of auto-splitting or due
> to users setting them up incorrectly to begin with.
