Kafka New Producer setting acks=2 in 0.8.2.1
Hi, The documentation for new producer allows passing ack=2(or any other numeric value) but when i actually pass anything other than 0,1,-1 in broker log i see following warning. Client producer-1 from /X.x.x.x:50105 sent a produce request with request.required.acks of 2, which is now deprecated and will be removed in next release. Valid values are -1, 0 or 1. Please consult Kafka documentation for supported and recommended configuration I have a particular use case where i want replication to be acknowledged by exactly (replicationFactor -1 ) broker or message publish should fail if that many Acks are not possible. regards

Hello, This behavior has been changed since 0.8.2.0, you can find the details in the following KIP discussion: https://cwiki.apache.org/confluence/display/KAFKA/KIP-1+-+Remove+support+of+request.required.acks And the related ticket is KAFKA-1555. For your use case you could set min.insync.replicas to replicationFactor - 1, see detailed description of this config here: http://kafka.apache.org/documentation.html#newproducerconfigs Guozhang On Thu, May 14, 2015 at 1:40 PM, pushkar priyadarshi priyadarshi.push...@gmail.com wrote: Hi, The documentation for new producer allows passing ack=2(or any other numeric value) but when i actually pass anything other than 0,1,-1 in broker log i see following warning.
