前言：

apache hadoop版本告一段落，现在安装新的cdh版本的hadoop

下载Hadoop和JDK

下载Hadoop地址：http://archive.cloudera.com/cdh5/cdh/5/hadoop-2.6.0-cdh5.7.0.tar.gz
下载jdk：注册甲骨文账号下载，推荐1.7版本

安装JDK

解压jdk压缩包

  tar -zxvf /home/hadoop/software/jdk-7u80-linux-x64.tar.gz -C /usr/java

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_80 
export PATH=$JAVA_HOME/bin:$PATH
#show path




hadoop:root:/usr/java:>source /etc/profile
hadoop:root:/usr/java:>java -version
java version "1.7.0_80"
Java(TM) SE Runtime Environment (build 1.7.0_80-b15)
