David J. Garcia created KAFKA-9568: -------------------------------------- Summary: Kstreams APPLICATION_SERVER_CONFIG is not updated with static membership Key: KAFKA-9568 URL: https://issues.apache.org/jira/browse/KAFKA-9568 Project: Kafka Issue Type: Bug Components: streams Affects Versions: 2.4.0 Reporter: David J. Garcia
A kstreams application with static membership, and StreamsConfg.APPLICATION_SERVER_CONFIG set, will NOT update old server config upon restart of application on new host. Steps to reproduce: # start two kstreams applications (with same consumer group) and enable static membership (and set application server config to <ip-addr>:<port>) # kill one of the applications and restart it on a new host(with new ip) before timeout ends (so that rebalancing doesn't occur). # the other kstreams application will now have an invalid application_server_config Possible fix: If an application restarts with a new host/identity..etc, it could trigger a "light-rebalance" where the other applications in the consumer group don't change partition assignments ,but instead just get their configuration updated. -- This message was sent by Atlassian Jira (v8.3.4#803005)
