stack commented on HBASE-15812:
-------------------------------
I don't follow. If I click on 'Metrics Dump', I get 500. In master branch, this
goes to /metrics. In branch-1 it goes to /jmx. If /jmx in master 'works'
showing metrics v2, why not hook up 'Metrics Dump' to /jmx instead of /metrics?
Maybe I am misunderstanding.
