--------------------------------------
Summary: New consumer should throw InvalidTopicException on poll
when invalid topic in metadata
Key: KAFKA-16764
URL: https://issues.apache.org/jira/browse/KAFKA-16764
Project: Kafka
Issue Type: Bug
Components: consumer
Affects Versions: 3.7.0
Reporter: Lianet Magrans
A call to consumer.poll should throw InvalidTopicException if an invalid topic
is discovered in metadata. This can be easily reproduced by calling
subscribe("invalid topic") and then poll, for example.The new consumer does not
throw the expected InvalidTopicException like the LegacyKafkaConsumer does.
The legacy consumer achieves this by checking for metadata exceptions on every
iteration of the ConsumerNetworkClient (see
