John Roesler commented on KAFKA-9248: ------------------------------------- Hey [~mjsax], I just saw this ticket. I think it's the same as https://issues.apache.org/jira/browse/KAFKA-9517, do you agree? If so, I'd close this one as a duplicate, since 9517 already has a PR. > Foreign key join does not pickup default serdes and dies with NPE > ----------------------------------------------------------------- > > Key: KAFKA-9248 > URL: https://issues.apache.org/jira/browse/KAFKA-9248 > Project: Kafka > Issue Type: Bug > Components: streams > Affects Versions: 2.4.0 > Reporter: Matthias J. Sax > Assignee: Matthias J. Sax > Priority: Major > > The foreign key join operator only works if `Serdes` are passed in by the > user via corresponding API methods. > If one tries to fall back to default Serdes from `StreamsConfig` the operator > does not pick up those Serdes but dies with a NPE. -- This message was sent by Atlassian Jira (v8.3.4#803005)
