单节点集群安装权限错误

  • 772

命令是 bin/start-all.sh

hadoop@user-HP-dx2480-MT-NA125PA:/usr/local/hadoop/hadoop$ bin/start-all.sh

错误是

mv: cannot move `/usr/local/hadoop/hadoop/bin/../logs/hadoop-hadoop-namenode-user-HP-dx2480-MT-NA125PA.out.4' to `/usr/local/hadoop/hadoop/bin/../logs/hadoop-hadoop-namenode-user-HP-dx2480-MT-NA125PA.out.5': Permission denied
mv: try to overwrite `/usr/local/hadoop/hadoop/bin/../logs/hadoop-hadoop-namenode-user-HP-dx2480-MT-NA125PA.out.4', overriding mode 0644 (rw-r--r--)? 
mv: try to overwrite `/usr/local/hadoop/hadoop/bin/../logs/hadoop-hadoop-namenode-user-HP-dx2480-MT-NA125PA.out.3', overriding mode 0644 (rw-r--r--)? 
mv: try to overwrite `/usr/local/hadoop/hadoop/bin/../logs/hadoop-hadoop-namenode-user-HP-dx2480-MT-NA125PA.out.2', overriding mode 0644 (rw-r--r--)?

有什么解决办法吗？？

hadoop

  1. 这似乎是一个权限问题。尝试使用sudo命令执行 start-all。

    1. 创建用户

        sudo addgroup hadoop    
  sudo adduser --ingroup hadoop hduser

    2. 添加以下行以将 hduser 添加到 sudoers 中，vi /etc/sudoers 

       hduser (ALL)=(ALL) ALL

    3. 更改 hadoop 所有者

       chown  -R hduser:hadoop hadoop

    where hduser→ 用户名, hadoop→ 组名
