Hi all,
We can use kafka-consumer-groups.sh to find group owner. Is there any tools
can find the producer for a given topic?
Thanks.
YuanjiaLi
A groupcoordinator is relating to a groupId from my understanding.
"AdminClient.findCoordinator" can find the groupcoordinator for a given groupId.

Hi Sa Li,
You can try to use jmxtrans+opentsdb to monitor kafka. Jmxtrans is collecting
data with JMX and sending to opentsdb. Opentsdb is graphing and alerting.

hi Chen,
Maybe you can take some tips from kafka.tools.KafkaMigrationTool.java, it's
also a multi-threads using case.
Reusing the same ConsumerConnector every time is ok. If you create
