Dataworks报错no such cmd splitVector

你好，MongoDB同步报如下问题：com.alibaba.datax.common.exception.DataXException Code[Framework-02], Description[The DataX engine encountered an error during running. For the specific cause, refer to the error diagnosis after DataX stops running. ]. - com.mongodb.MongoCommandException Command failed with error 59 'no such cmd splitVector' on server 1.madsdfdfstatus.comss. The full response is { ok 0.0, errmsg no such cmd splitVector, code 59 }

【问题原因】：因为某些版本的mongodb不支持splitVector。

【解决方案】：

1. 切换成单并发任务。

2. 任务转脚本模式，MongoDB读端添加配置 "useSplitVector":false。
