---------------------------------------
Summary: Consumer cannot rejoin to the group after rebalancing
Key: KAFKA-8104
URL: https://issues.apache.org/jira/browse/KAFKA-8104
Project: Kafka
Issue Type: Bug
Components: consumer
Affects Versions: 2.0.0
Reporter: Gregory Koshelev
TL;DR; {{KafkaConsumer}} cannot rejoin to the group due to inconsistent
{{AbstractCoordinator.generation}} (which is {{NO_GENERATION}} and
{{AbstractCoordinator.joinFuture}} (which is succeeded {{RequestFuture}}). See
explanation below.
There are 16 consumers in single process (threads from pool-4-thread-1 to
pool-4-thread-16). All of them belong to single consumer group
{{hercules.sink.elastic.legacy_logs_elk_c2}}. Rebalancing has been acquired and
consumers have got {{CommitFailedException}} as expected:
{{2019-03-10T03:16:37.023Z [pool-4-thread-10] WARN
r.k.vostok.hercules.sink.SimpleSink - Commit failed due to rebalancing
org.apache.kafka.clients.consumer.CommitFailedException: Commit cannot be
completed since the group has already rebalanced and assigned the partitions to
another member. This means that the time between subsequent calls to poll() was
longer than the configured max.poll.interval.ms, which typically implies that
the poll loop is spending too much time message processing. You can address
this either by increasing the session timeout or by reducing the maximum size
of batches returned in poll() with max.poll.records.
