我试图在Cloudera Hue界面中运行配置单元查询，它可以正常运行几百条记录。当我在更大的数据集上运行它时，它失败了。我尝试在互联网上搜索它，但看起来有很多类似的错误，但不是我正在寻找的确切解决方案。我在我的配置单元查询中使用了redexp_replace，我不认为这会导致任何异常（我的印象是它可以轻松处理字符串和NULL类型）
我得到的错误是java.util.regex.PatternSyntaxException：无与伦比的结束＆＃39;）＆＃39;接近指数12
更新： 这是导致问题的记录：
columnA：ReadData（或ListDirectory）
columnB：ListDirectory）
columnC：NULL
columnD：NULL
我的查询： regexp_replace（columnA，columnB，＆＃34;＆＃34;）作为columnA， B栏 regexp_replace（columnC，columnD，＆＃34;＆＃34;）作为columnC，
请让我知道我哪里出错了。
以下是日志中有趣的部分...... * .... [记录] ...

答案 0 :(得分：0)
我并不完全理解你想要完成的事情，但我可以告诉你，regex_replace的第二个参数需要是一个有效的正则表达式。
您传递的值不是有效的表达式。具体而言，ListDirectory) )，因为{{1}}是正则表达式中的保留符号。
