Tom Mau commented on KAFKA-9859: -------------------------------- Looks like the topic pattern it looking for in `kafka.tools.StreamsResetter#isInternalTopic` does not match the generated internal topic name [https://github.com/apache/kafka/blob/trunk/core/src/main/scala/kafka/tools/StreamsResetter.java#L679-L680] {code:java} topicName.endsWith("-subscription-registration-topic") topicName.endsWith("-subscription-response-topic"){code} > kafka-streams-application-reset tool doesn't take into account topics > generated by KTable foreign key join operation > -------------------------------------------------------------------------------------------------------------------- > > Key: KAFKA-9859 > URL: https://issues.apache.org/jira/browse/KAFKA-9859 > Project: Kafka > Issue Type: Bug > Components: streams, tools > Reporter: Levani Kokhreidze > Priority: Major > > Steps to reproduce: > * Create Kafka Streams application which uses foreign key join operation > * Stop Kafka streams application > * Perform `kafka-topics-list` and verify that foreign key operation internal > topics are generated > * Use `kafka-streams-application-reset` to perform the cleanup of your kafka > streams application: `kafka-streams-application-reset --application-id > <your_app_id> --input-topics <your_input_topic> --bootstrap-servers > <your_bootstrap_server> --to-datetime 2019-04-13T00:00:00.000` > * Perform `kafka-topics-list` again, you'll see that topics generated by the > foreign key operation are still there. > `kafka-streams-application-reset` uses `repartition` and `changelog` suffixes > to determine which topics needs to be deleted, as a result topics generated > by the foreign key are ignored. -- This message was sent by Atlassian Jira (v8.3.4#803005)
