hadoop Error: JAVA_HOME is not set and could not be found.

Hadoop安装完后，启动时报Error: JAVA_HOME is not set and could not be found.
解决办法：
        修改/etc/hadoop/hadoop-env.sh中设JAVA_HOME。
        应当使用绝对路径。
        export JAVA_HOME=$JAVA_HOME                  //错误，不能这么改
        export JAVA_HOME=/usr/local/lib/jdk1.8.0_60        //正确，应该这么改
