1. 借鉴

ubuntu 14.04 - Namenode not starting -su: /home/hduser/../libexec/hadoop-config.sh: No such file or directory

2. 开始

⑴ 格式化namenode时提示：libexec/hadoop-config.sh: No such file or directory]/dirname: missing operand

原因：

① 看下core-site.xml文件中的hadoop.tmp.dir配置的文件夹是否存在
② which没安装：yum install which

3. 大功告成
