> Project: Kafka
> Issue Type: Bug
> Reporter: Edoardo Comar
>
> A consumer that is manually assigned a topic-partition is able to consume
> messages that a consumer that subscribes to the topic can not.
> To reproduce : take the test
> EndToEndAuthorizationTest.testProduceConsume
> (eg the SaslSslEndToEndAuthorizationTest implementation)
>
> it passes ( = messages are consumed)
> if the consumer is assigned the single topic-partition
> consumers.head.assign(List(tp).asJava)
> but fails
> if the consumer subscribes to the topic - changing the line to :
> consumers.head.subscribe(List(topic).asJava)
> The failure when subscribed shows this error about synchronization:
> org.apache.kafka.common.KafkaException: Unexpected error from SyncGroup:
> Messages are rejected since there are fewer in-sync replicas than required.
> at
> org.apache.kafka.clients.consumer.internals.AbstractCoordinator$SyncGroupResponseHandler.handle(AbstractCoordinator.java:455)
> The test passes in both cases (subscribe and assign) with the setting
> this.serverConfig.setProperty(KafkaConfig.MinInSyncReplicasProp, "1")
