-----------------------------------
Summary: Mirror Maker Connectors leak admin clients used for topic
creation
Key: KAFKA-14443
URL: https://issues.apache.org/jira/browse/KAFKA-14443
Project: Kafka
Issue Type: Bug
Components: mirrormaker
Reporter: Greg Harris
Assignee: Greg Harris
the MirrorMaker connectors are each responsible for creating internal topics.
For example, the Checkpoint connector creates a forwarding admin and passes it
to a method to create the topic, but never closes the ForwardingAdmin or
delegate objects:
[https://github.com/apache/kafka/blob/13c9c78a1f4ad92023e8354069c6817b44c89ce6/connect/mirror/src/main/java/org/apache/kafka/connect/mirror/MirrorCheckpointConnector.java#L161-L164]
Instead, this object should be intentionally closed when it is no longer
needed, to prevent consuming resources in a running MM2 application.
