Ewen Cheslack-Postava commented on KAFKA-4809:
----------------------------------------------
The reason we want to make sure it works properly against 0.8.2 builds is
because it didn't exist there but we wanted to do upgrade testing. The upgrade
testing didn't get implemented until 0.9, but to do the input/output validation
we needed that class. So the scripts pull in the tools jar from a newer version
and use them against the older version of Kafka. We took care in doing this
such that the only thing being used from the newer version is that class.
We could certainly test more versions (though as this is just a basic sanity
check I'm not sure we need more than one case for each major version), but
since 0.8.2 requires special handling it's probably the most important of
these. (Although I also think most of the things under sanity_checks should be
disabled by default since they get exercised by the "real" tests anyway.)
> sanity_checks/test_verifiable_producer.py should test 0.10.x and not 0.8

> {{sanity_checks/test_verifiable_producer.py}} should test the latest 0.10.0,
> 0.10.1 and 0.10.2 releases. It should also not test 0.8.2.2, since there
> appears to be no {{VerifiableProducer}} class in Kafka 0.8.2.2.
