Jakob Homan reopened KAFKA-1980:
--------------------------------
> Console consumer throws OutOfMemoryError with large max-messages
> ----------------------------------------------------------------
>
> Key: KAFKA-1980
> URL: https://issues.apache.org/jira/browse/KAFKA-1980
> Project: Kafka
> Issue Type: Bug
> Components: tools
> Affects Versions: 0.8.1.1, 0.8.2.0
> Reporter: Håkon Hitland
> Priority: Minor
> Attachments: kafka-1980.patch
>
>
> Tested on kafka_2.11-0.8.2.0
> Steps to reproduce:
> - Have any topic with at least 1 GB of data.
> - Use kafka-console-consumer.sh on the topic passing a large number to --max-messages, e.g.:
> $ bin/kafka-console-consumer.sh --zookeeper localhost --topic test.large --from-beginning --max-messages 99999999 | head -n 40
> Expected result:
> Should stream messages up to max-messages
> Result:
> Out of memory error:

> As a first guess I'd say that this is caused by slice() taking more memory than expected. Perhaps because it is called on an Iterable and not an Iterator?
