[jira] [Commented] (HBASE-17774) Improve locality info in table details page

["Lars George (JIRA)" <ji...@apache.org>]

Lars George commented on HBASE-17774:
-------------------------------------

Sorry, did see HBASE-15675 later. I will consolidate what is missing here soon. But the locality and empty store files may still be an issue. Let me try out master and update this JIRA accordingly.

> The {{table.jsp}} page does list the locality info of each region, but is missing some vital other details, which are:
> - An extra column listing store and store file counts (could be two separate columns too like in Master and RS UI, but a single column saves space, for example "3/6", meaning three stores and six store files in total
> - Hide locality "0.0" if the stores are all empty, i.e. no store file is present. It makes little sense penalizing an empty store when it comes to the total locality of the table.
> - Make region name clickable like on RS status page, linking to {{region.jsp}} page showing store details.
> - Summary row at the end, showing the total locality (see note above), number stores, number of store files. That is, compute the _real_ locality, which is considering only the actual store files.
> I also wish we had some simple but effective charts/diagrams here, like a heatmap for data distribution within the table (since we have all of this info), or another heatmap for current request distribution. Strong +1 to add that here too.
> I have reasoned about this at customers way too often to not have this improved somehow. For the enterprise level admin, a good UI goes a long way!
