• 配置jdk环境变量

hadoop:root:/usr/java:>vi /etc/profile # /etc/profile # System wide environment and startup programs, for login setup # Functions and aliases go in /etc/bashrc # It's NOT a good idea to change this file unless you know what you # are doing. It's much better to create a custom.sh shell script in # /etc/profile.d/ to make custom changes to your environment, as this # will prevent the need for merging in future updates. #add path export JAVA_HOME=/usr/java/jdk1.7.0_80export PATH=$JAVA_HOME/bin:$PATH #show path hadoop:root:/usr/java:>source /etc/profile
hadoop:root:/usr/java:>java -version
