Vladimir Tretyakov commented on KAFKA-1481:
-------------------------------------------
Hi Jun Rao, look at http://search-hadoop.com/m/4TaT4lonIW
Example:
kafka.consumer:type="ZookeeperConsumerConnector",name="af_servers-af_servers-spm_new_cluster_topic-af_servers_wawanawna-Dell-1401353748289-fcaaea29-0-FetchQueueSize"
Look at part: "spm_new_cluster_topic-af_servers_wawanawna-Dell", what is
host name here "servers_wawanawna-Dell" or "wawanawna-Dell" ?
> Stop using dashes AND underscores as separators in MBean names

> Key: KAFKA-1481
> URL: https://issues.apache.org/jira/browse/KAFKA-1481
> Project: Kafka
> Issue Type: Bug
> Components: core
> Affects Versions: 0.8.1.1
> Reporter: Otis Gospodnetic
> Labels: patch
> Fix For: 0.8.2

> Attachments: KAFKA-1481_2014-06-06_13-06-35.patch

>
> 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.
