hello,
i've got a set of broker nodes running 0.8.2.1. on my laptop i'm also
running 0.8.2.1, and i have a single broker node and mirrormaker there.
i'm also using kafka-console-consumer.sh on the mac to display messages
on a favorite topic being published from the broker nodes. there are no
messages on the topic, but everything is well-behaved. i can inject
messages with kafkacat and everything is fine.
but then!
on the laptop i switched everything to 0.8.3 but left the broker nodes
alone. now when i run mirrormaker i see this:

if i use kafkacat to generate a message on the topic i see
IllegalArgumentExceptions instead.
this suggests that the two versions of kafka aren't compatible. is this
the case? does the whole ecosystem need to be on the same version?
thank you,
doug
- are 0.8.2.1 and 0.8.3 compatible? Doug Tomm
