hadoop集群部署配置补充

/etc/hosts
192.168.153.147 Hadoop-host
192.168.153.146 Hadoopnode1
::1 localhost

/etc/profile
export HADOOP_HOME=/opt/hadoop  
export PATH=$PATH:$HADOOP_HOME/bin

设置关键的分布式IP地址配置：
masters文件：
192.168.153.147
slaves文件：
192.168.153.147
192.168.153.146

将hadoop配置分发至hadoopnode1节点计算机
scp –r /opt/hadoop root@hadoopnode1 :/opt/

运行
hadoop namenode -format，格式化namenode

Hadoop启动命令：
start-all.sh
