> Clean up controller logging
> Key: KAFKA-794
> URL: https://issues.apache.org/jira/browse/KAFKA-794
> Project: Kafka
> Issue Type: Improvement
> Components: controller
> Affects Versions: 0.8
> Reporter: Neha Narkhede
> Assignee: Neha Narkhede
> Priority: Blocker
> Labels: kafka-0.8, p2
> We created the state change log in KAFKA-513 which creates a well formatted log of the lifetime of all state change requests in a Kafka cluster. While troubleshooting KAFKA-790, I looked into server.log, controller.log and state-change.log and realized we can improve the controller logging -
> 1. StopReplica state change is missing from the state-change.log
> 2. Some state change log messages are repeated. These are likely mistakenly inside a for loop rather than outside
> 3. Some controller logging that should be in the controller.log is still in server.log. For example, everything from ReplicaManager. This is useful for troubleshooting but confusing to be inside server.log.
