Yang Ye commented on KAFKA-457:
-------------------------------
The behaviour of the code is changed after kafka-369 is checked in, and the
system tests all work well. So this jira should be marked as resolved.
> Leader Re-election is broken in rev. 1368092
> --------------------------------------------
>
> Key: KAFKA-457
> URL: https://issues.apache.org/jira/browse/KAFKA-457
> Project: Kafka
> Issue Type: Bug
> Reporter: John Fung
> Assignee: Yang Ye
> Priority: Blocker
> Attachments: run-test.sh
>
>
> Steps to reproduce:
> 1. Check out rev. 1368092 and execute the command: $ ./sbt update package
> 2. Replace <kafka_home>/system_test/single_host_multi_brokers/bin/run-test.sh
> with the attached script because the logging message related to "shut down
> completed" and "leader state transition" has been modified in this revision.
> 3. Execute the command bin/run-test.sh
> 4. The test seems to be hung.
> 5. The reason is that there is no leader re-election happening after the
> first leader is terminated. By checking the logs, there may be only 1
> "completed the leader state transition" log message found in the server logs:
> $ grep "completed the leader state transition" *
> kafka_server_3.log:[2012-08-13 10:07:58,085] INFO Replica Manager on Broker
> 3, completed the leader state transition for topic mytest partition 0
> (kafka.server.ReplicaManager)
> 6. The correct behavior as in rev 1367821, re-election log messages are found
> after leader termination as follows:
> $ grep "completed the leader state transition" *
> kafka_server_1.log:[2012-08-13 09:40:23,542] INFO Broker 1 completed the
> leader state transition for topic mytest partition 0
> (kafka.server.ReplicaManager)
> kafka_server_1.log:[2012-08-13 09:42:17,881] INFO Broker 1 completed the
> leader state transition for topic mytest partition 0
> (kafka.server.ReplicaManager)
> kafka_server_2.log:[2012-08-13 09:40:29,082] INFO Broker 2 completed the
> leader state transition for topic mytest partition 0
> (kafka.server.ReplicaManager)
> kafka_server_3.log:[2012-08-13 09:44:06,695] INFO Broker 3 completed the
> leader state transition for topic mytest part
