> Running TopicCommand --alter causes connection close/reset errors in kafka
> logs
> -------------------------------------------------------------------------------
>
> Key: KAFKA-2127
> URL: https://issues.apache.org/jira/browse/KAFKA-2127
> Project: Kafka
> Issue Type: Bug
> Components: tools
> Reporter: Jason Rosenberg
> Priority: Minor
>
> I am using 0.8.2.1. I've been noticing that any time I use TopicCommand to
> alter a topic (e.g. add partitions) or delete a topic, the broker logs show a
> bunch of closed connections, and usually 2 or 3 Connection reset exceptions.
> It logs these with ERROR status.
> I recently used the kafka.admin.TopicCommand tool to increase the partitions
> for a topic from 1 to 4. So I ran:
> {code}
> java -cp kafka.jar kafka.admin.TopicCommand --zookeeper myzkserver:12345
> --topic mytopic --alter --partitions 4
> {code}
> This resulted in the following sequence in the broker log (repeated pretty
> much in the logs of each broker):
> {code}
