Fix for a wrong error returned on full metadata refresh before joining a consumer group #4678

Closed emasab closed 2 months ago

emasab commented 2 months ago

A metadata call before member joins consumer group, could lead to an UNKNOWN_TOPIC_OR_PART error. Solved by updating the consumer group following a metadata refresh only in safe states. Happening since 2.1.0

Closes #4589
