使用此链接,尝试在 ubuntu 12.04(64 位机器)中安装 Hadoop 版本 - 2.2.0(单节点集群)

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 致命的 namenode.NameNode:namenode 中的异常加入 java.lang.RuntimeException:org.xml.sax.SAXParseException;systemId:文件:/usr/local/hadoop/etc/hadoop/mapred-site.xml;行号:27;列号:1;结尾部分不允许有内容。

我需要做什么才能解决以下问题?

Mapred-site.xml:

可能是您忘记删除 XML 中的某些字符。请发布您的完整 XML。就像@Abhishek 说的!
