-----------------------------------
Summary: Protocol upgrade should allow empty member assignment in
group conversion
Key: KAFKA-17733
URL: https://issues.apache.org/jira/browse/KAFKA-17733
Project: Kafka
Issue Type: Sub-task
Reporter: Dongnuo Lyu
Assignee: Dongnuo Lyu
During conversion from classic to consumer group, if a member has empty
assignment (e.g., the member just joined and has never synced), the conversion
will fail because of the buffer underflow error when deserializing the member
assignment.
We should allow empty assignment while deserializing the member assignment.
