安装Hadoop

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。。。
