datax同步出现No operations allowed after connection closed

datax配置的是每天一个时间点同步，每次同步一个小时左右即可完成任务，下一次同步就报这个错误了，No operations allowed after connection closed，
mysql数据库服务设置的超时空闲连接为8小时，有办法可以不改动mysql空闲超时配置，改datax的哪里配置做到超时存活检测，自动重新连接来避免这个问题吗

Start by reproducing the scheduled DataX synchronization against MySQL with the server's eight-hour idle-connection timeout and capture when the connection closes. Inspect DataX's MySQL connection configuration and determine whether an idle-connection check or reconnect option exists; done means the next scheduled run succeeds without changing MySQL's timeout.
