stack commented on HBASE-10289:
-------------------------------
Tell me more [~nijel] In hbase-env.sh in trunk you can specify ports for JMX
(IIRC). Or are you talking about fixing the RMI madness where it picks a
random port to respond? With this patch in place, can we remove the talk in
hbase-env.sh of flags for starting JMX? What happens if someone passes the
flags? Will we have two JMX servers running?
Thanks for doing this.

>
> If we enable JMX MBean server for HMaster or Region server through VM
> arguments, the process will use one random which we cannot configure.
> This can be a problem if that random port is configured for some other
> service.
> This issue can be avoided by supporting a custom JMX Server.
> The ports can be configured. If there is no ports configured, it will
> continue the same way as now.
