【 使用环境 】生产环境
【 OB or 其他组件 】obbinlog
【 使用版本 】obbinlog-ce-4.2.3-200000012025021315.el7
【问题描述】在备租户上创建了Binlog Service 任务，但一直没有产生 binlog；
【复现路径】问题出现前后相关操作
通过ODP 连接备租户，执行 SHOW MASTER STATUS 可以看到 Position 一直为0
通过Flink CDC 连接ODP 获取binlog，则提示
position > file size 错误解决部分日志如下：
09:29:53 ERROR mysql.MySqlStreamingChangeEventSource: Error during binlog processing. Last offset stored = null, binlog reader near position = mysql-bin.000001/4
09:29:53 ERROR pipeline.ErrorHandler: Producer failure

在 Binlog 服务部署前提条件中，并未提及是否可以在备租户上创建 Binlog Service 任务
