Thanks for pulling up that list Jason ! I think that makes sense and
we can experiment with ZK 3.3.5. Not sure how widely 3.3.6 is tested
though.
Regarding the 3.4.x stability, the fact that serious issues are still
being reported makes me uncomfortable -
https://issues.apache.org/jira/browse/ZOO
According to the zookeeper home page, the current stable releases are
"3.3.6" and "3.4.4".
There seem to be a few interesting bug fixes in the release notes for 3.3.5
& 3.3.6:

Not really. Zookeeper 3.4.x is backwards compatible. Kafka 0.8 should
still work with any of the stable zookeeper versions out there. Once
ZK 3.4.x is stable, Kafka 0.8 would certainly benefit from the
If you do ./sbt make-pom, it generates a pom with the version set to 3.3.4.
And I do think that is the current version (if you look at the release
notes, I think for 0.7.1, it mentions that one of the changes is to upgrade
to 3.3.4 zookeeper client).

Ok,
So, there are known api changes that would preclude use of 3.4.x with
kafka, it sounds like?
Is there a notion of a supported version of zookeeper for each kafka
release?
How about upgrading the recommended version for 0.8 at least to the latest
3.3.x (3.3.6)?

I've been observing the zookeeper mailing list for 3.4.x and haven't
found it to be particularly stable. There are still serious issues
being reported like leader election failures, ephemeral node deletion.
I'm sure they are being fixed and there are many early adopters. But
my guess is that we sho
Jason,
We are just not sure about the stability of ZK 3.4.4. Does anybody know? In
fact, some of the features in ZK 3.4.x (like the multi operation) can
improve the availability of Kafka in 0.8. So, we'd like to move to ZK 3.4.4
if it's been widely used and is stable.
Thanks,

The ZooKeeper API has been stable for a while, I do not suspect there would be
any problems between 3.3.4 and 3.4.x. Personally, I have run Kafka 0.7.x with
ZooKeeper 3.4.3 with no problems
