hadoop - sudo hadoop 与 su hadoop

Question

有没有人遇到奇怪的环境问题，在调用 hadoop 命令时被迫使用 SU 而不是 SUDO？

sudo su -c 'hadoop fs -ls /' hdfs

Found 4 itemsdrwxr-xr-x   - hdfs   hdfs          0 2014-02-11 12:33 /appsdrwx------   - mapred hdfs          0 2014-03-10 10:25 /mapreddrwxrwxrwx   - hdfs   hdfs          0 2014-03-10 10:26 /tmpdrwxr-xr-x   - hdfs   hdfs          0 2014-02-11 12:34 /user

The environment allows finding of the executable:

sudo -u hdfs 'hadoop' 

Usage: hadoop [--config confdir] COMMANDwhere 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

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

将引号放在您的 hadoop 命令周围:

sudo -u hdfs hadoop fs -ls/
