Hi there- The error message returned when trying to produce to a nonexistent kafka topic (with auto topic creation disabled) is non obvious. It returns an error message of the form:
"org.apache.kafka.common.errors.TimeoutException: Failed to update metadata after xx ms" where xx is a small number, like 50. This looks like a communication error of some sort, except for the very short timeout. I went off into the weeds thinking that my kafka brokers were down or that there was a network routing problem or something until I finally figured out that the topic simply was not there. Creating the topic made this error go away and things started working. A more explicit exception like “org.apache.kafka.common.errors.NoSuchTopic: Unable to find topic ‘missing-topic-name-here’” would be much more straightforward. Richard
