Harsh J updated HBASE-4359:
---------------------------

    Attachment: HBase Master UI - Dead Servers (Yes, still dead).png
                HBASE-4359.r2.diff

Newer patch after a chat with Todd. Made it more consistent with the online listing.

In brightest day, in darkest night, no test case shall escape my sight:

> Unlike other components of the cluster, like NameNode and JobTracker pages, the HMaster's
info page does not show any data on dead region servers. While an RS is stateless being a
good reason not to count dead nodes, I think having a list of dead nodes helps in cases where
an administrator would want to find out which nodes are missing out on RS action (hey, everyone
likes consistently spiking graphs! ;)).
> Following HBASE-3580, I think it makes sense to have a list of already maintained dead
nodes show up in the info UI.
