Edoardo Comar created KAFKA-16931: ------------------------------------- Summary: A transient REST failure to forward fenceZombie request leaves Connect Task in FAILED state Key: KAFKA-16931 URL: https://issues.apache.org/jira/browse/KAFKA-16931 Project: Kafka Issue Type: Bug Components: connect Reporter: Edoardo Comar
When Kafka Connect runs in exactly_once mode, a task restart will fence possible zombies tasks. This is achieved forwarding the request to the leader worker using the REST protocol. At scale, in distributed mode, occasionally an HTTPs request may fail because of a networking glitch, reconfiguration etc Currently there is no attempt to retry the REST request, the task is left in a FAILED state and requires an external restart (with the REST API). Would this issue require a small KIP to introduce configuration entries to limit the number of retries, backoff times etc ? -- This message was sent by Atlassian Jira (v8.20.10#820010)
