FAQ
Cluster status and region topology visualization
------------------------------------------------

Key: HBASE-1805
URL: https://issues.apache.org/jira/browse/HBASE-1805
Project: Hadoop HBase
Issue Type: New Feature
Reporter: Andrew Purtell
Priority: Minor


There are several FOSS options for in-brower interactive data visualization. For example:
Protovis: http://vis.stanford.edu/protovis/
Flare: http://flare.prefuse.org/
Javascript InfoVis Toolkit: http://thejit.org/

The master GUI is of limited utility for dealing with really large tables or large clusters. It occurs to me looking over some of the examples/demos of the above that both HBase cluster status and region topology could be profitably rendered using such toolkits.

For example, go to the Flare demo page: http://flare.prefuse.org/demo . Click on Layouts. Iterate over the sub options. Could be rendering region structure ... navigate and click through for metadata. From there, hyperlink to actions or back to navigation. A pure Javascript example of something like this can be found here: http://thejit.org/Jit/Examples/Spacetree/example1.html

Go back to the Flare demo page. Click on Treemap. Another visualization suitable for tables. A pure Javascript analogue can be found here: http://thejit.org/Jit/Examples/Treemap/example2.html
