-----------------------------------
Summary: Improve locality info in table details page
Key: HBASE-17774
URL: https://issues.apache.org/jira/browse/HBASE-17774
Project: HBase
Issue Type: Improvement
Components: UI
Affects Versions: 1.3.0
Reporter: Lars George
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!
