---------------------------------------
Summary: Fix incorrect error message
Key: KAFKA-19540
URL: https://issues.apache.org/jira/browse/KAFKA-19540
Project: Kafka
Issue Type: Sub-task
Components: group-coordinator, streams
Affects Versions: 4.1.0
Reporter: Matthias J. Sax
When the new `streams.group` feature is enabled broker side, but
`group.coordinator.rebalance.protocols` config does disable "streams" protocol,
the client side error message is misleading:
{code:java}
rg.apache.kafka.common.errors.UnsupportedVersionException: The cluster does not
support the STREAMS group protocol or does not support the versions of the
STREAMS group protocol used by this client (used versions: 0 to 0). {code}
We should take a look to see if we can improve the error message. (Might not be
possible easily).
