-----------------------------------
Summary: KafkaServer leaks KafkaRaftManager when ZK migration
enabled
Key: KAFKA-15819
URL: https://issues.apache.org/jira/browse/KAFKA-15819
Project: Kafka
Issue Type: Bug
Components: kraft
Affects Versions: 3.6.0
Reporter: Greg Harris
Assignee: Greg Harris
In SharedServer, TestRaftServer, and MetadataShell, the KafkaRaftManager is
maintained as an instance variable, and shutdown when the outer instance is
shutdown. However, in the KafkaServer, the KafkaRaftManager is instantiated and
started, but then the reference is lost.
[https://github.com/apache/kafka/blob/49d3122d425171b6a59a2b6f02d3fe63d3ac2397/core/src/main/scala/kafka/server/KafkaServer.scala#L416-L442]
Instead, the KafkaServer should behave like the other call-sites of
KafkaRaftManager, and shutdown the KafkaRaftManager during shutdown.
