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-12], Description:[DataX插件初始化错误, 该问题通常是由于DataX安装错误引起，请联系您的运维解决 .]. - 插件加载失败，未完成指定插件加载:[ftpWriter, ftpreader]

Start with bin/datax.py and the sample job ../job/testjob.json, then trace the reported ConfigParser.parsePluginConfig and Engine entry points. Check why the ftpreader and ftpWriter plugins fail to initialize; done means the sample job loads both plugins and runs without Framework-12.
