[jira] [Created] (KAFKA-17733) Protocol upgrade should allow empty member assignment in group conversion

Dongnuo Lyu created KAFKA-17733:
-----------------------------------

             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.
