--------------------------------------
Summary: AsyncKafkaConsumer logs "Unexpected exception" for
timeouts during close
Key: KAFKA-19891
URL: https://issues.apache.org/jira/browse/KAFKA-19891
Project: Kafka
Issue Type: Bug
Reporter: Lucas Brutschy
The new consumer (in share, consumer and streams groups) log "unexpected
exception" at error log level when hitting a timeout during consumer close:
[https://github.com/apache/kafka/blob/trunk/clients/src/main/java/org/apache/kafka/clients/consumer/internals/AbstractHeartbeatRequestManager.java#L318]
[https://github.com/apache/kafka/blob/trunk/clients/src/main/java/org/apache/kafka/clients/consumer/internals/StreamsGroupHeartbeatRequestManager.java#L489]
This is confusing, since this is not really unexpected, and should probably be
logged at warn level at most.
