Chris Egerton created KAFKA-12474: ------------------------------------- Summary: Worker can die if unable to write new session key Key: KAFKA-12474 URL: https://issues.apache.org/jira/browse/KAFKA-12474 Project: Kafka Issue Type: Improvement Components: KafkaConnect Affects Versions: 2.4.2, 2.5.2, 2.8.0, 2.7.1, 2.6.2 Reporter: Chris Egerton Assignee: Chris Egerton
If a distributed worker is unable to write (and then read back) a new session key to the config topic, an uncaught exception will be thrown from its herder's tick thread, killing the worker. See [https://github.com/apache/kafka/blob/8da65936d7fc53d24c665c0d01893d25a430933b/connect/runtime/src/main/java/org/apache/kafka/connect/runtime/distributed/DistributedHerder.java#L366-L369] One way we can handle this case by forcing a read to the end of the config topic whenever an attempt to write a new session key to the config topic fails. -- This message was sent by Atlassian Jira (v8.3.4#803005)
