-----------------------------------
I am not too sure if this is applicable. Issue might not be necessary.
> Make KafkaConsumer compatible with multiple threads

> Key: KAFKA-7118
> URL: https://issues.apache.org/jira/browse/KAFKA-7118
> Project: Kafka
> Issue Type: Improvement
> Components: consumer
> Reporter: Richard Yu
> Priority: Major
> Labels: client, java, kip, needs-kip
>
> It was discovered that there is a performance constraint relating to
> {{KafkaConsumer#close()}}. When several cores are modifying the same
> consumer, a {{ConcurrentModification}} exception could result. This issue was
> first posted on Spark. For testing details, see SPARK-23636 and SPARK-19185.
> It would be preferable if multiple threads are allowed to modify one
> {{KafkaConsumer}}.
