一、背景

linux安装datax后，执行数据迁移任务报错。

datax自定义json内容如下：

{"job": {"setting": {"speed": {"channel": 3,"byte": 1048576},"errorLimit": {"record": 0,"percentage": 0.02}},"content": [{"reader": {"name": "mysqlreader","parameter": {"username": "root","password": "root","column": ["`id`","`app_name`","`title`","`order`","`address_type`","`address_list`"],"splitPk": "","connection": [{"table": ["job_group"],"jdbcUrl": ["jdbc:mysql://localhost:3306/dataxweb?useUnicode=true&characterEncoding=utf-8&useSSL=false"]}]}},"writer": {"name": "streamwriter","parameter": {"print": false,"encoding": "UTF-8"}}}]}
}

三、解决方法

删除运行json中的job.setting.speed.byte属性

删除后如下：

{"job": {"setting": {"speed": {"channel": 3},"errorLimit": {"record": 0,"percentage": 0.02}},"content": [{"reader": {"name": "mysqlreader","parameter": {"username": "root","password": "root","column": ["`id`","`app_name`","`title`","`order`","`address_type`","`address_list`"],"splitPk": "","connection": [{"table": ["job_group"],"jdbcUrl": ["jdbc:mysql://localhost:3306/dataxweb?useUnicode=true&characterEncoding=utf-8&useSSL=false"]}]}},"writer": {"name": "streamwriter","parameter": {"print": false,"encoding": "UTF-8"}}}]}
}
