Jiangjie Qin commented on KAFKA-5075: ------------------------------------- [~lindong] is currently working on the patch. Hopefully we can check that in this weekend. > The position in the consumers may be advanced incorrectly when some exception > is thrown from consumer.poll() > ------------------------------------------------------------------------------------------------------------ > > Key: KAFKA-5075 > URL: https://issues.apache.org/jira/browse/KAFKA-5075 > Project: Kafka > Issue Type: Bug > Components: clients, consumer > Affects Versions: 0.10.2.0 > Reporter: Jiangjie Qin > Assignee: Dong Lin > Fix For: 0.11.0.0 > > > In Fetcher.fetchRecords() we iterate over the partition data to collect the > ConsumerRecords, after we collect some consumer records from a partition, we > advance the position of that partition then move on to the next partition. If > the next partition throws exceptions (e.g. OffsetOutOfRangeException), the > messages that have already been read out of the buffer will not be delivered > to the users. Since the positions of the previous partitions have been be > updated, those messages will not be consumed again either. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
