通过时间宏变量+定时执行作业，可以实现数据库增量同步和文件增量同步。 如果配置了时间宏变量，通过DataArts Studio数据开发调度CDM迁移作业时，系统会将时间宏变量替换为“数据开发作业计划启动时间-偏移量”，而不是“CDM作业实际启动时间-偏移量”。 dateformat dateformat支持两种形式的参数：

选择KERBEROS鉴权时，需要配置MRS Manager的用户名和密码。从HDFS导出目录时，如果需要创建快照，这里配置的用户需要HDFS系统的管理员权限。 如果要创建MRS安全集群的数据连接，不能使用admin用户。因为admin用户是默认的管理页面用户，这个用户无法作为安全集
