我正在尝试让apache hadoop 1.21运行，但遇到了以下异常：

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

完整堆栈跟踪：

我已经寻找解决方案将近3天了，我发现了几个网站（比如这个：hadoop“failed to set setxincludeaware（true）for parser”error and how to resolve it），建议在maven依赖中添加xerces和xalan。也有其他网站，建议几乎相反-删除所有xerces引用类路径。但建议的解决方案中没有一个是有效的：（
我也试着说：

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

我正在使用ApacheHadoop1.21和JDK1.7.0-17。

在我的例子中，它是过时的maven组件依赖于 xerces-impl 2.4.0 （由于 mockrunner 1.0.3 用于测试阶段）。以下托管依赖项添加到 <dependencyManagemen> 部分帮助。

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