Ted Yu commented on HBASE-12559:
--------------------------------
Configuration doesn't provide method to persist changes made to an instance of
Configuration.
For testing, a subclass of Configuration needs to persist changes to the
hbase-site.xml which is on the classpath.
Not sure if the above approach is desirable.
> Provide LoadBalancer with online configuration capability

> 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.
