Description
我的操作是从oracle 中抽取数据,写入hive
现在问题是oracle 中某些字段含有特殊字符,与hive 字段分隔符相同,导致抽取后某些字段被分割,进而hive 内字段与值不对应(注,oracle 特殊字符较多,hive 无法找到有效的分隔符)
想问一下dataX 有没有什么解决办法,或者是改为多字符分隔符

Research direction
The issue concerns Oracle-to-Hive extraction when source values contain the Hive field delimiter, but it names no files, tests, or entry points. Start by tracing the Oracle extraction and Hive writing configuration, then reproduce a value containing the delimiter; done means field boundaries remain correct or the supported delimiter behavior is clearly documented.
