Taiyuan Zhang commented on KAFKA-3585:
--------------------------------------
I tried to reproduce the issue, but the shutting down is pretty fast for me,
and I don't see the error in the issue description.
My steps are:
1. Start zookeeper
2. Copy config/server.properties to two other files server-1 properties and
server-2.properties. 3 brokers use different log.dir, port and id.
3. Start the 3 brokers
4. Create a topic with 3 partition and 1 replication
5. Use producer command line to publish several messages
6. Use consumer command line verify the messages are published successfully
7. Close brokers one by one, and it's really fast, no errors shown.
> Shutdown slow when there is only one broker which is controller
