一、启动报错

datax 连接mysql报错，datax  No suitable driver found for ["jdbc:mysql:

报的驱动错误，如果已经安装了mysql相关的插件，一般是配置文件错误造成的。

如：（注意 reader 和 writer 的 jdbcUrl ，前者是个数组，后者是个字符串。本人把后者配置也成[] 报了上面的错误

    }
}

二、同步过程中报错

经DataX智能分析,该任务最可能的错误原因是:
com.alibaba.datax.common.exception.DataXException: Code:[Framework-14], Description:[DataX传输脏数据超过用户预期，该错误通常是由于源端数据存在较多业务脏数据导致，请仔细检查DataX汇报的脏数据日志信息, 或者您可以适当调大脏数据阈值 .].  - 脏数据条数检查不通过，限制是[0]条，但实际上捕获了[14]条.

看日志发现 "type":"LONG"  可能数据类型Long有关？
