As is, our naming is just broke. You can't have instances of different clusters on one machine. Our master bean is not uniquely named so you can't have multiple masters on the one machine.... ditto regionservers (The rpc servers publish their own bean distingushed by the port they run on which is better only should probably have master or regionserver prefix).
The name of our master bean is 'MasterStatistics' though its metrics only (even the operation is a reset on metrics).
Doing minimum so can get 0.92.1 in this issue but this stuff needs a revamp.
