在ubuntu中配置hadoop - linux报错
"
在ubuntu中配置hadoop时总是显示如下信息：
ubuntu:~$ bin/hadoop namenode -format
-bash: bin/hadoop: No such file or directory
hadoop@ubuntu :~$ bin/start-all.ssh
-bash: bin/start-all.ssh: No such file or directory
写回答
-
"
-bash: bin/hadoop: No such file or directory
是说bin/hadoop文件不存在，你切换到hadoop的目录下再执行
-bash: bin/start-all.ssh: No such file or directory
同样是文件不存在，应该是start-all.sh 不是.ssh
######非常感谢，上面的问题解决了，但又有问题出现了。
1 下面是运行了ghmin@ubuntu :~/hadoop$ bin/hadoop namenode -format后的情况

2 下面是运行了ghmin @ubuntu :~/hadoop$ bin/start-all.sh后的情况，到这一步就有出现问题了，改了半天权限竟然还是这样，在hadoop@ubuntu下也运行了，结果是一样的，还望大家指教，谢谢！starting namenode, logging to /home/ghmin/hadoop/libexec/../logs/hadoop-ghmin-namenode-ubuntu.out/home/ghmin/hadoop/bin/hadoop-daemons.sh: line 38: /home/ghmin/hadoop/bin/slaves.sh: Permission denied/home/ghmin/hadoop/bin/hadoop-daemons.sh: line 38: exec: /home/ghmin/hadoop/bin/slaves.sh: cannot execute: Permission denied/home/ghmin/hadoop/bin/hadoop-daemons.sh: line 38: /home/ghmin/hadoop/bin/slaves.sh: Permission denied/home/ghmin/hadoop/bin/hadoop-daemons.sh: line 38: exec: /home/ghmin/hadoop/bin/slaves.sh: cannot execute: Permission deniedjobtracker running as process 5862.
