Not sure were you exactly copied this. However, second paragraph here
https://kafka.apache.org/documentation/#upgrade_10_2_0 explains:
> Starting with version 0.10.2, Java clients (producer and consumer) have
acquired the ability to communicate with older brokers. Version 0.10.2 clients
can talk to version 0.10.0 or newer brokers. However, if your brokers are older
than 0.10.0, you must upgrade all the brokers in the Kafka cluster before
upgrading your clients. Version 0.10.2 brokers support 0.8.x and newer clients.
Ah. I see. You copied from the KIP.
The "Motivation" sections describes the state _before_ the change :)
I think we may be talking about different goals; if I understand correctly,
you’re discussing upgrading clients without upgrading brokers. I want to do the
opposite: upgrade brokers and leave the clients alone. It sounds like that
should work fine, right?
