Hi Johnny,

I haven't tried it yet so I am not 100% sure which one should be upgraded in 
what order but the way I think is - you can upgrade brokers when you are not 
upgrading ZK too.  so if that holds true then the sequence do not matter.
 Again I can be completely wrong here.May be some one else from the group can 
explain this in more detail.

Thank you,
Amit

RE: Kafka upgrade from 0.8.0 to 0.10.0.0

[ZHU Hua B]

Hi,


I have another question, for ZK upgrade, we just shut down it, update the new 
version, then restart it. If it is enough or there is any configuration need 
change? Thanks!

Johnny

What version of ZK are you using?

If you are using ZK 3.3, I'd recommend upgrading it before you upgrade Kafka.
If you are on ZK 3.4.5 or 3.4.6, you are good.

RE: Kafka upgrade from 0.8.0 to 0.10.0.0

[ZHU Hua B]

Hi,


The current ZK version is 3.3.4 (Kafka 0.8.0), we want to upgrade to 3.4.6 
(Kafka 0.10.0.0), do you mean it's better to upgrade ZK before upgrade Kafka? 
Thanks!






Best Regards

Johnny

Kafka upgrade from 0.8.0 to 0.10.0.0

[ZHU Hua B]

Hi,


For a rolling upgrade, Kafka suggest upgrade the brokers one at a time (shut 
down the broker, update the code, and restart it) to avoid downtime during the 
upgrade.
Usually, there is one zookeeper point to some brokers in a Kafka cluster, if 
the zookeeper should be upgraded also? If so, how to avoid downtime during 
zookeeper upgrade? Thanks!

Johnny
