[VOTE] 3.3.2 RC1

2022-12-21 Thread Chris Egerton
Hello Kafka users, developers and client-developers,

This is the second candidate for release of Apache Kafka 3.3.2.

This is a bugfix release with several fixes since the release of 3.3.1. A
few of the major issues include:

* KAFKA-14358 Users should not be able to create a regular topic name
__cluster_metadata
KAFKA-14379 Consumer should refresh preferred read replica on update
metadata
* KAFKA-13586 Prevent exception thrown during connector update from
crashing distributed herder


Release notes for the 3.3.2 release:
https://home.apache.org/~cegerton/kafka-3.3.2-rc1/RELEASE_NOTES.html

*** Please download, test and vote by Friday, January 6, 2023, 10pm UTC
(this date is chosen to accommodate the various upcoming holidays that
members of the community will be taking and give everyone enough time to
test out the release candidate, without unduly delaying the release)

* Maven artifacts to be voted upon:

* Javadoc:

* Tag to be voted upon (off 3.3 branch) is the 3.3.2 tag:
https://github.com/apache/kafka/releases/tag/3.3.2-rc1

* Documentation:
https://kafka.apache.org/33/documentation.html

* Protocol:
https://kafka.apache.org/33/protocol.html

The most recent build has had test failures. These all appear to be due to
flakiness, but it would be nice if someone more familiar with the failed
tests could confirm this. I may update this thread with passing build links
if I can get one, or start a new release vote thread if test failures must
be addressed beyond re-running builds until they pass.

Unit/integration tests:
https://ci-builds.apache.org/job/Kafka/job/kafka/job/3.3/142/testReport/

José, would it be possible to re-run the system tests for 3.3 on the latest
commit for 3.3 (e3212f2), and share the results on this thread?

Cheers,

Chris


Delete Kafka topics replicated by mirror maker 2

2022-12-21 Thread Shirolkar, Anup



Hi Team,

I have configured two Kafka clusters with 2-way replication using MirrorMaker2 
(mm2).
I want to delete a topic from source cluster and its replica from destination 
cluster.

When I delete a topic in the source cluster and then delete the replica in the 
destination cluster, the destination cluster replica reappears.

I have set auto.create.topic.enable=false in both source and target cluster.

To test this behaviour is due to mm2, I stopped all the mm2 services and then 
deleted the destination source and destination topics.
The destination topic was gone but as soon as I start the mm2 service it 
recreates the destination topic even when the source topic does not exist.

I am using Kafka 2.7.0 for both Kafka clusters as well as mm2.
Can someone let me know what I need to change to delete a topic and its replica.



Thanks.
