Hi Amit,
Thanks for your info! Best Regards Johnny -----Original Message----- From: Amit Tank [mailto:amittankopensou...@gmail.com] Sent: 2016年11月16日 0:33 To: users@kafka.apache.org Subject: Re: Kafka upgrade from 0.8.0 to 0.10.0.0 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.
