Hadoop2.5.2环境搭建系统为64位，启动hdfs: ./sbin/start-dfs.sh报错

按照网上教程的操作尝试搭建伪分布式，在启动hadoop时（./sbin/start-dfs.sh）报错如下：

Starting namenodes on [localhost]
localhost: starting namenode, logging to /opt/hadoop-2.5.2/logs/hadoop-root-namenode-xxw-node01.localdomain.out

希望各位帮忙解决一下，不胜感激！

hdfs的环境变量没有配置

增加下面红字部分。

首先vi /etc/profile,

#设置jdk的安装路径
    export JAVA_HOME=/opt/lib64/jdk1.8.0_20
    #指定CLASSPATH和PATH
    export CLASSPATH=$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib
    export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH:$HOME/bin
    #设置的hadoop的环境变量
    export HADOOP_HOME=/opt/lib64/hadoop-2.5.1
    export PATH=$HADOOP_HOME/bin:$PATH
   export PATH=$HADOOP_HOME/sbin:$PATH
    export CLASSPATH=$HADOOP_HOME/lib:$CLASSPATH

奥，谢谢啦

应该是环境变量的问题，我也遇到这个问题了。
还有个办法自己检查，在shell中自己通过echo调试。
