Travis Thompson updated HDFS-6105:
----------------------------------
Attachment: datanodes-tab.png
I can reproduce it in 2.3.0. If I open the NN page and (with the Firefox
console open) I click on the "Datanodes" tab, 3 GETs are sent to http://nn/jmx
very quickly. I've attached an image of the Firefox console. Using Firefox
27.0.1 on Mac OS 1.8.5
> NN web UI for DN list loads the same jmx page multiple times.

> When loading "Datanodes" page of the NN web UI, the same jmx query is made
> multiple times. For a big cluster, that's a lot of data and overhead.
