Randall Hauch commented on KAFKA-4667:
--------------------------------------
Per [~ewencp], I created
[KIP-153|https://cwiki.apache.org/confluence/display/KAFKA/Kafka+Improvement+Proposals]
to address the new distributed worker configuration properties.
> Connect should create internal topics
> -------------------------------------
>
> Key: KAFKA-4667
> URL: https://issues.apache.org/jira/browse/KAFKA-4667
> Project: Kafka
> Issue Type: Bug
> Components: KafkaConnect
> Reporter: Emanuele Cesena
> Assignee: Randall Hauch
> Priority: Critical
> Fix For: 0.11.0.0
>
>
> I'm reporting this as an issue but in fact it requires more investigation
> (which unfortunately I'm not able to perform at this time).
> Repro steps:
> - configure Kafka for consistency, for example:
> default.replication.factor=3
> min.insync.replicas=2
> unclean.leader.election.enable=false
> - run Connect for the first time, which should create its internal topics
> I believe these topics are created with the broker's default, in particular:
> min.insync.replicas=2
> unclean.leader.election.enable=false
> but connect doesn't produce with acks=all, which in turn may cause the
> cluster to go in a bad state (see, e.g.,
> https://issues.apache.org/jira/browse/KAFKA-4666).
> Solution would be to force availability mode, i.e. force:
> unclean.leader.election.enable=true
> when creating the connect topics, or viceversa detect availability vs
> consistency mode and turn acks=all if needed.
> I assume the same happens with other kafka-based services such as streams.
