问题描述
有人在遇到hadoop命令时遇到了一个奇怪的环境问题并被迫使用SU而不是SUDO吗?
Has anybody got into a strange environment issue and been forced to use SU rather than SUDO when calling hadoop commands?
sudo su -c 'hadoop fs -ls /' hdfs
Found 4 items
drwxr-xr-x - hdfs hdfs 0 2014-02-11 12:33 /apps
drwx------ - mapred hdfs 0 2014-03-10 10:25 /mapred
drwxrwxrwx - hdfs hdfs 0 2014-03-10 10:26 /tmp
drwxr-xr-x - hdfs hdfs 0 2014-02-11 12:34 /user
环境允许查找可执行文件:
The environment allows finding of the executable:
sudo -u hdfs 'hadoop'
Usage: hadoop [--config confdir] COMMAND
where COMMAND is one of:
namenode -format format the DFS filesystem
...
fs run a generic filesystem user client
...
...
Most commands print help when invoked w/o parameters.
sudo -u hdfs 'hadoop fs -ls /'
sudo: hadoop fs -ls: command not found
我想知道这是否是环境问题，但这没有给我任何提示:
I wondered if it was an environment issue, but this gave me no hints:
sudo su -c 'env' hdfs | sort >sudo_su.txt
sudo -u hdfs 'env' | sort >sudo.txt
diff sudo.txt sudo_su.txt

推荐答案
在您的hadoop命令周围加上引号:
Drop the quotes around your hadoop command:
sudo -u hdfs hadoop fs -ls /
