Apache Hadoop setXIncludeAware UnsupportedOperationException

我正在尝试运行 Apache Hadoop 1.21，但出现以下异常：

Failed to set setXIncludeAware(true) for parser org.apache.xerces.jaxp.DocumentBuilderFactoryImpl
org.apache.xerces.jaxp.DocumentBuilderFactoryImpl@2662e5cf:java.lang.UnsupportedOperationException

完整的堆栈跟踪：

我已经寻找解决方案近3天了，我找到了几个网站（比如这个：Hadoop“无法为解析器设置 setXIncludeAware(true)”错误以及如何解决该错误 http://caffeinbean.wordpress.com/2011/03/01/hadoop-failed-to-set-setxincludeawaretrue-for-parser-error-and-how-to-resolve-it/），建议将 xerces 和 xalan 添加到 Maven 依赖项。还有其他网站，建议几乎相反 - 从类路径中删除所有 xerces 引用。但建议的解决方案均无效:(

我也尝试过：

System.setProperty("javax.xml.parsers.DocumentBuilderFactory", "com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl"); 

到我的代码。但这也没有帮助:(

正如我所说，我正在使用 Apache Hadoop 1.21 和 JDK 1.7.0-17。

就我而言，它是过时的 Maven 组件依赖项xerces-impl 2.4.0（由于mockrunner 1.0.3用于测试阶段）。添加以下托管依赖项<dependencyManagemen>部分有帮助。

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>xerces</groupId>
            <artifactId>xercesImpl</artifactId>
            <version>2.11.0</version>
        </dependency>
    </dependencies>
</dependencyManagement>

Hadoop 版本是2.3.0. 这是另一篇文章 http://caffeinbean.wordpress.com/2011/03/01/hadoop-failed-to-set-setxincludeawaretrue-for-parser-error-and-how-to-resolve-it/其中描述了类似的情况。
