The org.reflections is removed, so the initial logger of worker is only "root". However, the e2e needs a non-root logger to verify dynamic logger
We can add a logger to connect_log4j.properties to fix this e2e. For example:
log4j.logger.org.apache.kafka.clients.consumer.ConsumerConfig=ERROR
this can make admin/logger return two logger - org.apache.kafka.clients.consumer.ConsumerConfig and root

We plan to remove all ZooKeeper-related code in version 4.0. However, some old brokers in the end-to-end tests still require ZooKeeper service, so we need to run the ZooKeeper service using the 3.x release instead of the dev branch.
Since version 3.9 is not available in the https://s3-us-west-2.amazonaws.com/kafka-packages repo, we can use version 3.8 for now.

This PR removes ZK test parameterizations from ducktape by:
- Removing zk from quorum.all_non_upgrade
- Removing quorum.zk from @matrix and @parametrize annotations
- Changing usages of quorum.all to quorum.all_kraft
- Deleting message_format_change_test.py

KIP-853 adds support for dynamic KRaft quorums. This means that the quorum topology is
no longer statically determined by the controller.quorum.voters configuration. Instead, it
is contained in the storage directories of each controller and broker.
Users of dynamic quorums must format at least one controller storage directory with either
the --initial-controllers or --standalone flags. If they fail to do this, no quorum can be
established. This PR changes the storage tool to warn about the case where a KIP-853 flag has
not been supplied to format a KIP-853 controller. (Note that broker storage directories
can continue to be formatted without a KIP-853 flag.)
There are cases where we don't want to specify initial voters when formatting a controller. One
example is where we format a single controller with --standalone, and then dynamically add 4
more controllers with no initial topology. In this case, we want the 4 later controllers to grab
the quorum topology from the initial one. To support this case, this PR adds the
--no-initial-controllers flag.

This change fixes a few issues.
KAFKA-17608; KRaft controller crashes when active controller is removed
When a control batch is committed, the quorum controller currently increases the last stable offset but fails to create a snapshot for that offset. This causes an issue if the quorum controller renounces and needs to revert to that offset (which has no snapshot present). Since the control batches are no-ops for the quorum controller, it does not need to update its offsets for control records. We skip handle commit logic for control batches.
KAFKA-17604; Describe quorum output missing added voters endpoints
Describe quorum output will miss endpoints of voters which were added via AddRaftVoter. This is due to a bug in LeaderState's updateVoterAndObserverStates which will pull replica state from observer states map (which does not include endpoints). The fix is to populate endpoints from the lastVoterSet passed into the method.

Kafka Streams system tests were failing with this error:
Failed to parse host name from entry 3001@d for the configuration controller.quorum.voters. Each entry should be in the form `{id}@{host}:{port}`.
The cause is that in kafka.py line 876, we create a delimited string from a list comprehension, but the input is a string itself, so each character gets appended vs. the bootstrap server string of host:port. To fix this, this PR adds split(',') to controller_quorum_bootstrap_servers. Note that this only applies when dynamicRaftQuorum=False

why df04887ba5 does not fix it?
The fix of df04887ba5 is to NOT collect the log from path `/mnt/kafka/kafka-operational-logs/debug/xxxx.log`if the task is successful. It does not change the log level. see ducktape b2ad7693f2/ducktape/tests/test.py (L181)
why df04887ba5 does not see the error of "sort"
df04887ba5 does NOT show the error since the number of features is only "one" (only metadata.version). Hence, the bug is not triggered as it does not need to "sort". Now, we have two features - metadata.version and krafe.version - so the sort is executed and then we see the "hello bug"
why we should change the kafka.log_level to INFO?
the template of log4j.properties is controlled by `log_level` (https://github.com/apache/kafka/blob/trunk/tests/kafkatest/services/kafka/templates/log4j.properties#L16), and the bug happens in writing debug message (e4ca066680/core/src/main/scala/kafka/server/metadata/BrokerMetadataListener.scala (L274)). Hence, changing the log level to DEBUG can avoid triggering the bug.

Because of KIP-902 (Upgrade Zookeeper version to 3.8.2), it is not possible to upgrade from a Kafka version
earlier than 2.4 to a version later than 2.4. Therefore, we should not test these upgrade scenarios
in upgrade_test.py. They do happen to work sometimes, but only in the trivial case where we don't
create topics or make changes during the upgrade (which would reveal the ZK incompatibility).
Instead, we should test only supported scenarios.

This patch re-introduces the `group.version` feature flag and gates the new consumer rebalance protocol with it. The `group.version` feature flag is attached to the metadata version `4.0-IV0` and it is marked as production ready. This allows system tests to pick it up directly by default without requiring to set `unstable.feature.versions.enable` in all of them. This is fine because we don't plan to do any incompatible changes before 4.0.

This patch makes the new group coordinator, introduced as part of KIP-848, the default. This means that any KRaft cluster created from trunk defaults to using the new group coordinator.

7496e62434 fixed an error that caused an exception to be thrown on broker startup when debug logs were on. This made it to every version except 3.2.

When becoming the active KRaftMigrationDriver, there is another race condition similar to KAFKA-16171. This time, the race is due to a stale read from ZK. After writing to /controller and /controller_epoch, it is possible that a read on /migration is not linearized with the writes that were just made. In other words, we get a stale read on /migration. This leads to an inability to sync metadata to ZK due to incorrect zkVersion on the migration ZNode.
The non-linearizability of reads is in fact documented behavior for ZK, so we need to handle it.
To fix the stale read, this patch adds a write to /migration after updating /controller and /controller_epoch. This allows us to learn the correct zkVersion for the migration ZNode before leaving the BECOME_CONTROLLER state.
This patch also adds a check on the current leader epoch when running certain events in KRaftMigrationDriver. Historically, we did not include this check because it is not necessary for correctness. Writes to ZK are gated on the /controller_epoch zkVersion, and RPCs sent to brokers are gated on the controller epoch. However, during a time of rapid failover, there is a lot of processing happening on the controller (i.e., full metadata sync to ZK and full UMRs sent to brokers), so it is best to avoid running events we know will fail.
There is also a small fix in here to improve the logging of ZK operations. The log message are changed to past tense to reflect the fact that they have already happened by the time the log message is created.

This patch partially reverts `group.version` in trunk. I kept the `GroupVersion` class but removed it from `Features` so it is not advertised. I also kept all the changes in the test framework. I removed the logic to require `group.version=1` to enable the new consumer rebalance protocol. The new protocol is enabled based on the static configuration.
For the context, I prefer to revert it in trunk now so we don't forget to revert it in the 3.9 release. I will bring it back for the 4.0 release.

We weren't enabling discoverBrokerVersions to check the supported versions in the AddPartitionsToTxnManager. This means that any verification request (or any AddPartitionsToTxnRequest version) from a newer broker would fail when sending to an older broker.
The bulk of this change is adding additional transactions system tests for old versions.
One test upgrades the cluster completely. This didn't catch the issue but could be useful.
The other test forces a new broker to send a verification request to an older one. Without the discoverBrokerVersions change, all tests between mixed brokers failed. (We introduced a new request version in 3.8 -- which is a separate version from the one that caused the bug for 3.5 -> 3.6) With the addition, the tests all passed.
I also manually ran a test for 3.5 -> 3.6 since the issue there was slightly different and was caused by the unstableLatestVersion flag being enabled. This change should fix this as well. 👍

Minor change to how the describe topic output is parsed in system tests, to ensure that the output is preserved, even if only some fields are relevant to the test for now (which is what the test used to do before recent changes)
Initial problem: System tests were parsing the describe topic output in kafka.py assuming all fields would include a value. The describe API was recently changed, breaking this logic, because it included new fields for which there may not be values (ex. LastKnownElr).
Initial fix: The initial fix for this was to drop all fields from the output except for the ones currently used in the test, where in reality only the fields without values are the problematic ones.
Proposed improvement: A more extensible approach would be to drop only the fields that have no values and preserve the full output, which is what the test did before the initial fix mentioned above. This allows to easily extend the test to include more fields as needed, which could follow as the describe API and tests evolves (it will only require to add the fields to the returned value when needed, without having to change how the fields object is stripped).
Reviewers: Lucas Brutschy <lbrutschy@confluent.io>
In two tests, we are using the current snapshot version as a test parameter
`to_version`, but as the only option. We can hardcode it. This
simplifies testing downstream, since the test parameters do not change
with every version. In particular, some tests downstream are blacklisted
because they do not work with ARM. These lists need to be updated every
time `DEV_VERSION` is bumped.
Reviewers: Matthias J. Sax <matthias@confluent.io>
This fixes a consumer system test that was failing for the new protocol. The failure was because the test was expecting the eager behaviour of partitions being revoked on every rebalance, and it was wrongfully applying it to the runs with the new protocol too.
This same situation was previously identified and fixed in other parts of the sys test with #15661.

Consumer Rolling Upgrade is meant to test the protocol upgrade for the old protocol. Therefore, I am removing old changes.
Reviewers: Lucas Brutschy <lbrutschy@confluent.io>
Updating consumer system test that was failing with the new protocol, related to static membership behaviour. The behaviour regarding static consumers that join with conflicting group instance id is slightly different between the classic and new consumer protocol, so the expectations in the tests needed to be updated.
If static members join with same instance id:
Classic protocol: all members join the group with the same group instance id, and then the first one will eventually fail (receives a HB error with FencedInstanceIdException)
Consumer protocol: new member with an instance Id already in use is not able to join, and first member remains active (new member with same instance Id receives an UnreleasedInstanceIdException in the response to the HB to join the group)
This PR is keeping the single parametrized test that existed before, given that what's being tested and part of the test itself apply to all protocols. This is just updating the expectations that are different, based on the protocol parameter.
