[jira] [Created] (KAFKA-5997) acks=all does not seem to be honoured
Ronald van de Kuil created KAFKA-5997:
-----------------------------------------
Summary: acks=all does not seem to be honoured
Key: KAFKA-5997
URL: https://issues.apache.org/jira/browse/KAFKA-5997
Project: Kafka
Issue Type: Bug
Components: producer
Affects Versions: 0.11.0.0
Reporter: Ronald van de Kuil
I have a 3 node Kafka cluster. I made a topic with 1 partition with a replication factor of 2.
The replicas landed on broker 1 and 3.
When I stopped the leader I still could produce on it. Also, I saw the consumer consume it.
I produced with acks=all:
[main] INFO org.apache.kafka.clients.producer.ProducerConfig - ProducerConfig values:
acks = all
The documentations says says about acc=all:
"This means the leader will wait for the full set of in-sync replicas to acknowledge the record."
The producer api returns the offset which is present in the Metadatarecord.
I would have expected that producer could not publish because only 1 replica is in sync.
This is the output of the topic state:
Topic:topic1 PartitionCount:1 ReplicationFactor:2 Configs:
Topic: topic1 Partition: 0 Leader: 1 Replicas: 1,3 Isr: 1
I am wondering whether or not this is a bug in the current version of the API or whether the documentation (or my understanding) is eligible for an update? I expect the former.
If there is anything that I can do, please let me know.
