Question

使用此链接，尝试在ubuntu 12.04（64位计算机）中安装Hadoop版本 - 2.2.0（单节点群集）

http://bigdatahandler.com/hadoop-hdfs/installing-single-node-hadoop-2-2-0-on-ubuntu/

使用以下命令通过namenode格式化hdfs文件系统

hadoop namenode -format

当我这样做时，得到以下问题，

14/08/07 10:38:39 FATAL namenode.NameNode：namenode join中的异常 java.lang.RuntimeException：org.xml.sax.SAXParseException; systemId：file：/usr/local/hadoop/etc/hadoop/mapred-site.xml; lineNumber：27; columnNumber：1;尾随部分不允许使用内容。

为了解决以下问题，我需要做些什么？

Mapred-site.xml中：

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>

您可能忘记删除XML中的某些特性。请发布完整的XML。就像@Abhishek说的那样！
