[jira] [Created] (KAFKA-12318) system tests need to fetch Topic IDs
via Admin Client instead of via ZooKeeper
Ron Dagostino created KAFKA-12318:
-------------------------------------
Summary: system tests need to fetch Topic IDs via Admin Client instead of via ZooKeeper
Key: KAFKA-12318
URL: https://issues.apache.org/jira/browse/KAFKA-12318
Project: Kafka
Issue Type: Task
Components: system tests
Affects Versions: 3.0.0, 2.8.0
Reporter: Ron Dagostino
https://github.com/apache/kafka/commit/86b9fdef2b9e6ef3429313afbaa18487d6e2906e#diff-2b222ad67f56a2876410aba3eeecd78e8b26217192dde72a035c399dc4d3988bR1033-R1052 introduced a topic_id() function in the system tests. This function is currently coded to talk directly to ZooKeeper. This will be a problem when running a Raft-based metadata quorum -- ZooKeeper won't be available. This method needs to be rewritten to leverage the Admin Client.
This does not have to be fixed in 2.8 -- the method is only used in upgrade/downgrade-related system tests, and those system tests aren't being performed for Raft-based metadata quorums in the release (Raft-based metadata quorums will only be alpha/preview functionality at that point with upgrades/downgrades unsupported). But it probably will have to be fixed for the next release after that.
