      Description

      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.
