> Key: NIFI-14117
> URL: https://issues.apache.org/jira/browse/NIFI-14117
> Project: Apache NiFi
> Issue Type: Bug
> Affects Versions: 2.1.0
> Reporter: Nick M
> Assignee: Paul Grey
> Priority: Major
> Time Spent: 10m
> Remaining Estimate: 0h
>
> # Consume via ConsumeKafka in FLOW_FILE strategy
> # Check that kafka.key attribute is filled (it' ok)
> # Flow to PublishKafka topic with name 'dst'
> In source topic I got keys. Also in termediate queue I've check that
> kafka.key attribute is set.
> But in in kafka 'dst' topic I got no key on messages.
>
> If I manually set 'Kafka Key' property to 'kafka.key' that it work as
> expected and in destination topic I got messages with keys.
>
> I expect that by default key would be copied as it mention in description:
> _If not specified, the FlowFile attribute 'kafka.key' is used as the message
> key, if it is present._
>
> So we need one of:
> # Or fix default behaviour to adjust to processor description
> # Or fix description to remove default behaviour.
