[jira] [Created] (ACCUMULO-2878) Add JMX metrics to Master

Josh Elser created ACCUMULO-2878:
------------------------------------

             Summary: Add JMX metrics to Master
                 Key: ACCUMULO-2878
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-2878
             Project: Accumulo
          Issue Type: Improvement
          Components: master
            Reporter: Josh Elser
             Fix For: 1.7.0


We don't presently have any JMX metrics coming out of the master aside from very low-level statistics on the raw thrift calls.

The master has loads of really useful high-level information that we would want to track like, alive-tservers/total-tservers, active migrations, offlne tablets, assigned but offline tablets, etc. It could also serve as the centralized view point for "system wide" insight like FATE ops so that each tserver in a system doesn't report information on those.
