Philip Zeyliger commented on HADOOP-6977:
-----------------------------------------

Separating out the presentation and the data in dfshealth.jsp would be a boon 
all around.  It would make testing easier, and it would open the way for 
supporting other (XML, JSON, whatever) ways to get at those things.  +1 for the 
idea.

> The HDFS web user interface serves useful information through dfshealth.jsp 
> and dfsnodelist.jsp.
> The Herriot interface to Hadoop cluster daemons would benefit from the 
> addition of some way to channel metics information.
