本文介绍了一个关于Hadoop中使用Xerces解析器遇到的问题及解决方案。错误表现为无法设置XIncludeAware属性，原因是存在jar包冲突。解决办法是移除自定义的xercesImpl.jar，转而使用JDK自带的解析器。

ERROR org.apache.hadoop.conf.Configuration: Failed to set setXIncludeAware(true) for parser org.apache.xerces.jaxp.DocumentBuilderFactoryImpl@104faf8:java.lang.UnsupportedOperationException: This parser does not support specification "null" version "null"

原因：

jar包冲突

解决方法：

删除自己的xercesImpl.jar，用jdk自身的编译器，问题解决了
