Kuan Po Tseng commented on KAFKA-18160: --------------------------------------- Hi [~chia7712] , may I take over this issue if you are not working on it ? Will file a PR ASAP, thanks ! > Interrupting or waking up onPartitionsAssigned in AsyncConsumer can cause the > ConsumerRebalanceListenerCallbackCompletedEvent to be skipped, potentially > leading to corrupted added partitions > ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- > > Key: KAFKA-18160 > URL: https://issues.apache.org/jira/browse/KAFKA-18160 > Project: Kafka > Issue Type: Sub-task > Reporter: Chia-Ping Tsai > Assignee: Chia-Ping Tsai > Priority: Blocker > > I noticed this issue when testing KAFKA-17962. It includes two bugs listed > below. > *ConsumerRebalanceListenerCallbackCompletedEvent is skipped* > `invokeRebalanceCallbacks`could throw WakeupException/InterruptException [0] > and they are NOT handled. Hence, the event > `ConsumerRebalanceListenerCallbackCompletedEvent` is NOT sent to background > thread. > *Solution*: We should use try-catch blocks to propagate both > InterruptedException and WakeupException to the background thread. > *corrupted added partitions* > In the next iteration of invokeRebalanceCallbacks, non-fetchable assigned > partitions are treated as owned partitions [1]. This results in "empty" > partitions being passed to the listener, meaning that the listener never > receives the correctly added partitions after the first execution fails. > Consequently, this causes the test_pause_and_resume_sink (KAFKA-17962) to > become unstable when using AsyncConsumer. > *Solution*: We should add only partitions where pendingOnAssignedCallback is > false to the owned partitions. > [0] > https://github.com/apache/kafka/blob/2d39d5be64d4f5b6446f4b9ec3f32b039707d9d1/clients/src/main/java/org/apache/kafka/clients/consumer/internals/AsyncKafkaConsumer.java#L2046 > [1] > https://github.com/apache/kafka/blob/2d39d5be64d4f5b6446f4b9ec3f32b039707d9d1/clients/src/main/java/org/apache/kafka/clients/consumer/internals/AbstractMembershipManager.java#L828 -- This message was sent by Atlassian Jira (v8.20.10#820010)
