hadoop安装时core-site.xml的配置问题

[chugx2005]

请各位大牛帮忙：

这几天刚接触linux和hadoop.在安装hadoop时配置core-site.xml文件时没发现问题，但是格式化时提示core-site.xml配置错误。下面是core-site.xml的配置文件：
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>

<!-- Put site-specific property overrides in this file. -->

</configuration>
<property>
<name>fs.defaultFS</name>
<value>hdfs://chugx:9000</value>
</property>


<property>
<name>hadoop.tmp.dir</name>
<value>file:/home/chugx/hadoop</value>
</property>


<configuration>

下面是编译错误的提示：

谢谢大家。

请大家帮忙看看，这个问题困扰我好多天了，不甚感激，没想到安装hadoop都这么麻烦！

[荒-于嬉]

吧配置文件的<configuration>和</configuration>位置替换一下

[B lack.]

<configuration> <!-- NameNode的路径 --> <!-- Hadoop 1.x 的版本默认使用的端口是9000; Hadoop 2.x 的版本默认使用的端口是8020 --> <property> <name>fs.defaultFS</name> <value>hdfs://vmmain:8020</value> </property> <!-- HDFS集群上的数据,在Linux上保存的路径 --> <!-- 这个路径, 默认在/tmp/hadoop-root --> <property> <name>hadoop.tmp.dir</name> <value>/usr/local/hadoop/tmp</value> </property> </configuration>
