仿照如上文章进行了环境搭建
内容大致总结为
1. 配置集群内ssh免密码互相登录。请参照http://www.cnblogs.com/vigarbuaa/p/3579291.html
2. 安装hadoop. 配置如下文件
core-site.xml/mapred-site.xml/hdfs-site.xml/hadoop-env.sh/masters/slaves
3. 格式化namenode
root@kali:/data/hadoop/bin# hadoop namenode -format DEPRECATED: Use of this script to execute hdfs command is deprecated. Instead use the hdfs command for it. 14/03/03 21:56:52 INFO namenode.NameNode: STARTUP_MSG: /************************************************************
4. 启动服务
root@kali:/data/hadoop/sbin# ./start-all.sh This script is Deprecated. Instead use start-dfs.sh and start-yarn.sh Starting namenodes on [192.168.0.100] 192.168.0.100: ssh: connect to host 192.168.0.100 port 22: Connection refused The authenticity of host '192.168.0.101 (192.168.0.101)' can't be established.

5. 验证服务是否启动
