> Key: FLUME-3031
> URL: https://issues.apache.org/jira/browse/FLUME-3031
> Project: Flume
> Issue Type: Bug
> Components: Sinks+Sources, Test
> Affects Versions: v1.7.0
> Reporter: Attila Simon
> Assignee: Attila Simon
> Fix For: v1.8.0
>
>
> SequenceGeneratorSource uses a counter to construct the body of the generated
> Events which counter is not reseted when writing event to channel failed.
> This can lead to a situation that the total number of unique events at
> destination (if deduplication relies on msg body) is bigger than the
> totalEvents configuration parameter due to the retries.
> Fix should make sure that number of events at destination after filtering out
> the duplicates is equal to the configured value.
