Subject: Random continuous TimeoutException with Topic not present on one
KafkaProducer out of many in multithreaded env
Hello Everyone,
We are using Kafka 2.8.1 Broker/Client system in our prod env.
Getting following exception randomly after 1 hour or so for one Realtime
transfer from Kafka Producer to broker out of 5. (Rest 4 are working fine.)
java.util.concurrent.ExecutionException:
org.apache.kafka.common.errors.TimeoutException: Topic realtimeImport_1 not
present in metadata after 250 ms.

Due to this exception the realtime resources are not getting transfer to Kafka
Consumer. We are using following config on Kafka Broker:
group.initial.rebalance.delay.ms=0
listeners=SASL_PLAINTEXT://0.0.0.0:9092
log.retention.minutes=15
delete.topic.enable=true

security.protocol=SASL_PLAINTEXT
authorizer.class.name=kafka.security.auth.SimpleAclAuthorizer
allow.everyone.if.no.acl.found=true
zookeeper.set.acl=true
Can anyone please help us in finding the root cause for it?
