Ted Yu updated HBASE-12559:
---------------------------
Description:
StochasticLoadBalancer has many knobs which user can adjust.
It would increase productivity by allowing StochasticLoadBalancer to accept
online configuration changes.
LoadBalancer already implements setConf(Configuration) method which reloads
relevant configuration parameters.
We need to add updateMasterConfiguration() method to Admin which invokes the
setConf() method.

StochasticLoadBalancer should implement PropagatingConfigurationObserver and
reload relevant configuration parameters in onConfigurationChange() method.
