Joel Koshy commented on KAFKA-1481:
-----------------------------------
[~junrao] For 80.2, I believe the additional registration will not create any
new mbeans. i.e., it should be a no-op.
For 83, we could have one set of mbeans per port right? Or do you think that
would be too much? Your suggestion is to drop the port and just unify right?
That should also be good.
Also, [~vladimir.tretyakov] your patch needs a rebase as mentioned earlier.
> Stop using dashes AND underscores as separators in MBean names

> MBeans should not use dashes or underscores as separators because these
> characters are allowed in hostnames, topics, group and consumer IDs, etc.,
> and these are embedded in MBeans names making it impossible to parse out
> individual bits from MBeans.
> Perhaps a pipe character should be used to avoid the conflict.
> This looks like a major blocker because it means nobody can write Kafka 0.8.x
> monitoring tools unless they are doing it for themselves AND do not use
> dashes AND do not use underscores.
