-----------------------------------

             Summary: Missing topic causes service shutdown without exception
                 Key: KAFKA-7970
                 URL: https://issues.apache.org/jira/browse/KAFKA-7970
             Project: Kafka
          Issue Type: Bug
          Components: streams
    Affects Versions: 2.1.0
            Reporter: Jonny Heavey


When launching a KafkaStreams application that depends on a topic that doesn't exist, the streams application correctly logs an error such as:

"<TOPIC_NAME> is unknown yet during rebalance, please make sure they have been pre-created before starting the Streams application."

The stream is then shutdown, however, no exception is thrown indicating that an error has occurred.

In our circumstances, we run our streams app inside a container. The streams service is shutdown, but the process is not exited, meaning that the container does not crash (reducing visibility of the issue).

As no exception is thrown in the missing topic scenario described above, our application code has no way to determine that something is wrong that would then allow it to terminate the process.

 

Could the StreamsThread:onPartitionsAssigned method throw an exception when it decides to shutdown the stream (somewhere around line 264)?
