Kafka 2.4.0 & Mirror Maker 2.0 Error
Hi All,
I'm trying to set up mirror maker 2.0 with Kafka 2.4.0 however, I'm receiving the following errors on startup:
ERROR Plugin class loader for connector 'org.apache.kafka.connect.mirror.MirrorSourceConnector' was not found. Returning: org.apache.kafka.connect.runtime.isolation.DelegatingClassLoader@187eb9a8 (org.apache.kafka.connect.runtime.isolation.DelegatingClassLoader)
ERROR Plugin class loader for connector 'org.apache.kafka.connect.mirror.MirrorHeartbeatConnector' was not found. Returning: org.apache.kafka.connect.runtime.isolation.DelegatingClassLoader@187eb9a8 (org.apache.kafka.connect.runtime.isolation.DelegatingClassLoader)
ERROR Plugin class loader for connector 'org.apache.kafka.connect.mirror.MirrorCheckpointConnector' was not found. Returning: org.apache.kafka.connect.runtime.isolation.DelegatingClassLoader@187eb9a8 (org.apache.kafka.connect.runtime.isolation.DelegatingClassLoader)
I've checked the jar file containing these class file is in the class path.
Is there anything I need to add to plugin.path for the connect properties when running mirror maker?
Many Thanks,
Jamie

Hi,
I just tested with 2.4.0 release, I still get the same error.
Filed the jira ticket: https://issues.apache.org/jira/browse/KAFKA-9376
Thanks,

I pulled the 2.4 branch from github—version 2.4.1-snapshot of pom.xml. When I packaged it and ran it, I still found the same problem. But the data and offset could be synchronized to the target cluster.

Re: Kafka 2.4.0 & Mirror Maker 2.0 Error
Posted by Ryanne Dolan <ry...@gmail.com>.
Hey Jamie, are you running the MM2 connectors on an existing Connect
cluster, or with the connet-mirror-maker.sh driver? Given your question
about plugin.path I'm guessing the former. Is the Connect cluster running
2.4.0 as well? The jars should land in the Connect runtime without any need
to modify the plugin.path or copy jars around.
