Ismael Juma commented on KAFKA-18648:
-------------------------------------
It turns out that kafka-python actually needs metadata v0 as well:

> kafka-python requires metadata request version 0

> URL: https://issues.apache.org/jira/browse/KAFKA-18648
> Project: Kafka
> Issue Type: Bug

>
> KIP-896 captured protocol api support from a few clients including
> kafka-python. However, when we actually test a client, unexpected
> dependencies can sometimes be uncovered.
> It turns out that kafka-python has a path where the metadata version used is
> hardcoded to be v0 or v1:
> [https://github.com/dpkp/kafka-python/blob/a6d0579d3cadd3826dd364b01bc12a2173139abc/kafka/client_async.py#L835]
> We need to decide whether we keep the existing behavior in 4.0/trunk and
> update the KIP to reflect that kafka-python won't work without a (small)
> change or add back support for Metadata request v1-v3.
> I also filed an issue with kafka-python-ng (which is a fork of the original
> that is not abandoned).
