Chia-Ping Tsai created KAFKA-16639: -------------------------------------- Summary: AsyncKafkaConsumer#close does not send heartbeat to leave group Key: KAFKA-16639 URL: https://issues.apache.org/jira/browse/KAFKA-16639 Project: Kafka Issue Type: Bug Reporter: Chia-Ping Tsai Assignee: Chia-Ping Tsai
This bug can be reproduced by immediately closing a consumer which is just created. The root cause is that we skip the new heartbeat used to leave group when there is a in-flight heartbeat request ([https://github.com/apache/kafka/blob/5de5d967adffd864bad3ec729760a430253abf38/clients/src/main/java/org/apache/kafka/clients/consumer/internals/HeartbeatRequestManager.java#L212).] It seems to me the simple solution is that we create a heartbeat request when meeting above situation and then send it by pollOnClose ([https://github.com/apache/kafka/blob/5de5d967adffd864bad3ec729760a430253abf38/clients/src/main/java/org/apache/kafka/clients/consumer/internals/RequestManager.java#L62).] -- This message was sent by Atlassian Jira (v8.20.10#820010)
