> Kafka Channel Should Not Commit Offsets When Stopping
> -----------------------------------------------------
>
> Key: FLUME-2920
> URL: https://issues.apache.org/jira/browse/FLUME-2920
> Project: Flume
> Issue Type: Bug
> Components: Channel
> Affects Versions: v1.6.0
> Reporter: Kevin Conaway
> Priority: Critical
> Attachments: FLUME-2920.patch
>
>
> The Kafka channel commits the consumer offsets when shutting down (via stop()
> -> decommissionConsumerAndRecords())
> This can lead to data loss if the channel is shut down while messages have
> been fetched in a transaction but the transaction has not yet been committed.
> The only time that the offsets should be committed is when a transaction is
> complete.
