1）我们有3个节点kafka和kafka连接集群

2）我们仅在分布式模式下在kafka节点上运行kafka-connect

3）当我尝试使用以下配置创建连接器时：

    {
      "name": "connector-state-0",
      "config": {
        "connector.class": "io.debezium.connector.mysql.MySqlConnector",
        "database.user": "user",
        "database.server.id": "5023",
        "database.hostname": "hostname",
        "database.password": "password",
        "database.history.kafka.bootstrap.servers": "ip:9092",
        "database.history.kafka.topic": "topicname",
        "database.server.name": "prod",
        "database.port": "3306",
        "snapshot.mode": "when_needed",
        "include.schema.changes": "false",
        "table.whitelist": "country.state"
    }
   }

在创建连接器的请求中，它在3个节点中的2个上给我以下错误：

{"error_code":409,"message":"Cannot complete request because of a conflicting operation (e.g. worker rebalance)"}

在节点之一上：我能够创建连接器，但任务未启动，并且我可以在日志中看到以下错误：
