[jira] [Created] (KAFKA-9636) Simple join of two KTables fails
Paul Snively created KAFKA-9636:
-----------------------------------
Summary: Simple join of two KTables fails
Key: KAFKA-9636
URL: https://issues.apache.org/jira/browse/KAFKA-9636
Project: Kafka
Issue Type: Bug
Components: streams
Affects Versions: 2.4.1
Reporter: Paul Snively
Attachments: merge_issue.zip
Attempting to join two KTables yields a `Topology` that, when tested with `TopologyTestDriver` by adding records to the two `TestInputTopic`s, results in an empty `TestOutputTopic`.
I'm attaching a very small reproduction. The code is in Scala. The project is therefore an "sbt" project. You can reproduce the results from your shell with `sbt test`. The failure output will include the `describe` of the `Topology` in question.
