第一次尝试在自己的笔记本上安装单机的Hadoop，啥也不懂，上网瞎搜，找到个“超详细”版的文章，相当给力。
我之前安装过OpenJDK，所以跳过了安装SUN-JDK这一步，而$JAVA_HOME的位置也有所不同，我的位置在
/usr/lib/jvm/java-1.7.0-openjdk-i386
Hadoop的版本我下载的是1.1.2，要下载stable版本的，不然话找不到配置文件位置。
hadoop-1.1.2.tar.gz
其它的都大同小异，配置和启动过程都差不多。
对为啥要安装ssh服务不太理解，网上搜了下，貌似是因为namenode管理各个datanode的启动和停止都是通过无密码验证的ssh来进行的，参考内容在这里。
以后可以抽空在hadoop上玩玩儿了。。。
