Andrey updated KAFKA-6189:
--------------------------
Summary: Loosing messages on OFFSET_OUT_OF_RANGE error in consumer (was:
Loosing messages while getting OFFSET_OUT_OF_RANGE error in consumer)
> Loosing messages on OFFSET_OUT_OF_RANGE error in consumer
> ---------------------------------------------------------
>
> Key: KAFKA-6189
> URL: https://issues.apache.org/jira/browse/KAFKA-6189
> Project: Kafka
> Issue Type: Bug
> Components: clients
> Affects Versions: 0.11.0.0
> Reporter: Andrey
> Attachments: kafkaLossingMessages.png
>
>
> Steps to reproduce:
> * Setup test:
> ** producer sends messages constantly. If cluster not available, then it will
> retry
> ** consumer polling
> ** topic has 3 partitions and replication factor 3.
> ** min.insync.replicas=2
> ** producer has "acks=all"
> ** consumer has default "auto.offset.reset=latest"
> ** consumer manually commitSync offsets after handling messages.
> ** kafka cluster has 3 brokers
> * Kill broker 0
> * In consumer's logs:
> {code}
> 2017-11-08 11:36:33,967 INFO
> org.apache.kafka.clients.consumer.internals.Fetcher - Fetch offset
> 10706682 is out of range for partition mytopic-2, resetting offset
> [kafka-consumer]
> 2017-11-08 11:36:33,968 INFO
> org.apache.kafka.clients.consumer.internals.Fetcher - Fetch offset
> 8024431 is out of range for partition mytopic-1, resetting offset
> [kafka-consumer]
> 2017-11-08 11:36:34,045 INFO
> org.apache.kafka.clients.consumer.internals.Fetcher - Fetch offset
> 8029505 is out of range for partition mytopic-0, resetting offset
> [kafka-consumer]
> {code}
> After that, consumer lost several messages on each partition.
> Expected:
> * return upper bound of range
> * consumer should resume from that offset instead of "auto.offset.reset".
> Workaround:
> * put "auto.offset.reset=earliest"
> * get a lot of duplicate messages, instead of lost
> Looks like this is what happening during the recovery from broker failure
> (see attachment)
