Varsha Abhinandan updated KAFKA-8673:
-------------------------------------
Description:
We observed a deadlock kind of a situation in our Kafka streams application
when we accidentally shut down all the brokers. The Kafka cluster was brought
back in about an hour.
Observations made :
# Normal Kafka producers and consumers started working fine after the brokers
were up again.
# The Kafka streams applications were stuck in the "rebalancing" state.
# The Kafka streams apps have exactly-once semantics enabled.
# The stack trace showed most of the stream threads sending the join group
requests to the group co-ordinator
# Few stream threads couldn't initiate the join group request since the call
to
[org.apache.kafka.clients.producer.KafkaProducer#sendOffsetsToTransaction|https://jira.corp.appdynamics.com/browse/ANLYTCS_ES-2062#sendOffsetsToTransaction%20which%20was%20hung]
was stuck.
# Seems like the join group requests were getting parked at the coordinator
since the expected members hadn't sent their own group join requests
# And after the timeout, the stream threads that were not stuck sent a new
join group requests.
# Maybe (6) and (7) is happening infinitely
# Sample values of the GroupMetadata object on the group co-ordinator
# The list of notYetJoinedMembers client id's matched with the threads waiting
for their offsets to be committed.
