HADOOP_HDFS_HOME not found!
，这是什么情况？？？
执行这个命令：
export HADOOP_HDFS_HOME="$HADOOP_HOME"
建议Linux基础加强，多看些安装部署文档

执行这个命令：
export HADOOP_HDFS_HOME="$HADOOP_HOME"
vi /etc/profile
然后添加了
export JAVA_HOME=/usr/lib/jvm/jdk1.7.0_51
export HADOOP_PREFIX=/usr/hadoop-2.4.0
export CLASSPATH=".:$JAVA_HOME/lib:$CLASSPATH"
export PATH="$JAVA_HOME/:$HADOOP_PREFIX/bin:$PATH"
export HADOOP_PREFIX PATH CLASSPATH
export HADOOP_HOME="$/usr/hadoop-2.4.0"
export PATH=$HADOOP_HOME/bin:$PATH
export HADOOP_HDFS_HOME="$HADOOP_HOME"
还是提示HADOOP_HDFS_HOME not found!
这是怎么回事呢

不需要加上引号，然后记得文件生效
执行下面命令
source 文件名如果不行，最好重启下集群，或则虚拟机

配置core_site.xml是不是这样写
<configuration><property><name>fs.default.name</name><value>hdfs://localhost:9000</value></property> <property><name>dfs.namenode.name.dir</name><value>file:/root/usr/hadoop-2.4.0/dfs/name</value></property> <property><name>dfs.datanode.data.dir</name><value>file:/root/usr/hadoop-2.4.0/dfs/data</value></property></configuration>
一直提示文档中根元素后面的标记必须格式正确。不知道什么情况
FATAL conf.Configuration: error parsing conf core-site.xml
org.xml.sax.SAXParseException; systemId: file:/root/usr/hadoop-2.4.0/etc/hadoop/core-site.xml; lineNumber: 22; columnNumber: 2; 文档中根元素后面的标记必须格式正确。
这是我的core-site.xml 配置，安装的是hadoop2.5.1

export JAVA_HOME=/usr/lib/jvm/jdk1.7.0_51
我都是 export PATH 在后面，不知道是不是顺序问题
