hadoop安装

rz -be

tar -xvzf hadoop-2.7.1.tar.gz

vi /etc/profile

export JAVA_HOME=/home/skinglzw/jdk1.8.0_101

export HADOOP_INSTALL=/home/skinglzw/hadoop-2.7.1

export PATH=$JAVA_HOME/bin:$PATH:$HADOOP_INSTALL/bin:$HADOOP_INSTALL/sbin

export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

source /etc/profile

如果是配置用户环境变量，则在~/.bashrc 文件中添加ZK_HOME,执行如下命令：

vim ~/.bashrc

然后重新登录linux终端，便可生效
