---------------------------------

             Summary: Multi noded with kraft combined mode will fail shutdown
                 Key: KAFKA-14287
                 URL: https://issues.apache.org/jira/browse/KAFKA-14287
             Project: Kafka
          Issue Type: Bug
          Components: kraft
    Affects Versions: 3.3.1
            Reporter: Luke Chen
            Assignee: Luke Chen


Multiple nodes with kraft combined mode (i.e. process.roles='broker,controller') can startup successfully. When shutdown in combined mode, we'll unfence broker first. When the remaining controller nodes are less than quorum size (i.e. N / 2 + 1), the unfence record will not get committed to metadata topic successfully. So the broker will keep waiting for the shutdown granting response and then timeout error:
