-----------------------------------
Summary: UnknownTopicOrPartitionException should be an instance of
InvalidMetadataException
Key: KAFKA-2246
URL: https://issues.apache.org/jira/browse/KAFKA-2246
Project: Kafka
Issue Type: Bug
Reporter: Jiangjie Qin
Assignee: Jiangjie Qin
In new producer, if a message send failed, we only refresh metadata when the
exception is an instance of InvalidMetadataException.
UnknownTopicOrPartitionException should be a sub class of it instead of just
RetriableException. The scenario we saw is that when a topic get deleted from
broker, UnkownTopicOrPartitionException will be thrown. Assuming auto topic
creation is turned on, supposedly the producer will be able to produce with
retries after the topic get recreated. But because
UnknownTopicOrPartitionException is not an instance of
InvalidMetadataException, producer will not refresh metadata and retries are
exhausted.
