Konstantin Boudnik commented on HADOOP-6977:
--------------------------------------------
bq. Separating out the presentation and the data in dfshealth.jsp would be a
boon all around
The idea of this one is slightly different: instead of making *.jsp better
modeled I'm going to provide a way for a system test to reach JMX beans and
pull down any information available there. I agree that built-in testability is
a better answer for many problems, however this fix is about making already
available information be visible in the cluster testing.
