I edit the first line of file "~/Software/Development/Hadoop/hadoop-0.20.2/bin/hadoop-daemon.sh" and then execute bin/start-all.sh, it displays the following message:
........... ........... slave1: /home/maohong/Software/Development/Hadoop/hadoop-0.20.2/bin/hadoop-daemon.sh: line 39: dirname: command not found slave1: /home/maohong/Software/Development/Hadoop/hadoop-0.20.2/bin/hadoop-daemon.sh: line 42: /home/maohong/Software/Development/Hadoop/hadoop-0.20.2/hadoop-config.sh: No such file or directory slave1: /home/maohong/Software/Development/Hadoop/hadoop-0.20.2/bin/hadoop-daemon.sh: line 75: mkdir: command not found slave1: Usage: hadoop-daemon.sh [--config <conf-dir>] [--hosts hostlistfile] (start|stop) <hadoop-command> <args...> .......... .......... It seems that the problem lies in the first line of the file /bin/hadoop-daemon.sh. What do you think? How to configure it correctly ? 在 2010-03-23二的 21:23 +0800，liu chang写道： > On Tue, Mar 23, 2010 at 9:11 PM, 毛宏 <[email protected]> wrote: > > I use "file /usr/bin/env" to check if /usr/bin/env is present in my > > system and the answer is yes. > > But why does it still display > > datanode1:/usr/bin/env : bash: No such file or directory > > datanode2:/usr/bin/env : bash: No such file or directory ? > > Can you execute the 'bash' command at your shell?
