-------------------------------------
Summary: KafkaConsumer with auto commit enabled gets stuck when
killed after broker is dead
Key: KAFKA-3879
URL: https://issues.apache.org/jira/browse/KAFKA-3879
Project: Kafka
Issue Type: Bug
Reporter: Ashish K Singh
Assignee: Ashish K Singh
KafkaConsumer with auto commit enabled gets stuck when killed after broker is
dead.
* KafkaConsumer on close tries to close coordinator.
* Coordinator, if auto commit is enabled, tries to commit offsets synchronously
before closing.
* While trying to synchronously commit offsets, coordinator checks if
coordinator is alive by sending {{GroupCoordinatorRequest}}. As brokers are
dead, this returns {{NoAvailableBrokersException}}, which is a retriable
exception.
* Coordinator ready check enters into an infinite loop as it keeps retrying to
discover group coordinator.
