Shlomi, You should always upgrade brokers before clients. Newer versions of clients aren't guaranteed to work with older versions of brokers.
For scala versions, there is no functional difference. Generally you only need to worry about the Scala version if you are using the old clients (which are in the core jar) and the rest of your app requires a specific Scala version. -Ewen On Wed, Dec 23, 2015 at 6:31 AM, Shlomi Hazan <shl...@viber.com> wrote: > Hi All, > > Does someone has experience / encountered any issues using a 0.8.2.2 > producer against a 0.8.1.1 broker (specifically kafka_2.9.2-0.8.1.1)? > I want to upgrade my existing producer (0.8.2-beta). > Also, is there a functional difference between the scala versions > (2.9.2,2.10,2.11)? > > Thanks, > Shlomi > -- Thanks, Ewen
