运行简单shell脚本时出错

Question

试图运行一个简单的shell脚本，其中包含我经常执行的一组命令来设置我的Hadoop环境。首先，我通过'ssh localhost'连接，然后手动执行这些命令，我​​想自动执行此过程，我正在执行以下操作，这会导致下面列出的错误。请注意我可以通过命令提示符手动执行这些命令。请帮助我。

我做什么

$sudo chmod 777 hadoop-startup-script.sh 
$ssh localhost 
$./hadoop-startup-script.sh 

这将导致以下错误

(~($))sh hadoop-startup-script.sh 
hadoop-startup-script.sh: 2: cd: can't cd to /home/hadoop/hadoop-0.20.204.0 
hadoop-startup-script.sh: 3: hadoop-startup.sh: bin/hadoop: not found 
hadoop-startup-script.sh: 4: hadoop-startup.sh: bin/start-all.sh: not found 
hadoop-startup-script.sh: 5: hadoop-startup.sh: bin/hadoop: not found 
hadoop-startup-script.sh: 6: hadoop-startup.sh: bin/hadoop: not found 
hadoop-startup-script.sh: 7: hadoop-startup.sh: bin/hadoop: not found 
hadoop-startup-script.sh: 8: hadoop-startup.sh: bin/hadoop: not found 
hadoop-startup-script.sh: 9: hadoop-startup.sh: bin/hadoop: not found 
hadoop-startup-script.sh: 10: hadoop-startup.sh: bin/hadoop: not found 

的hadoop-startup-script.sh

#! /bin/bash 
cd ~/hadoop-0.20.204.0 
bin/hadoop namenode -format 
bin/start-all.sh 
bin/hadoop fs -mkdir input 
bin/hadoop fs -mkdir input/oreilly 
bin/hadoop fs -put /home/hadoop/Dropbox/hadoop/hadoop-inputs/oreilly-programmingPig/*.* /user/hadoop/input/oreilly/ 
bin/hadoop fs -put /home/hadoop/Dropbox/hadoop/hadoop-inputs/oreilly-programmingPig/NYSE_dividends /user/hadoop/input/oreilly/ 
bin/hadoop fs -put /home/hadoop/Dropbox/hadoop/hadoop-inputs/oreilly-programmingPig/baseball /user/hadoop/input/oreilly/ 
bin/hadoop fs -put /home/hadoop/Dropbox/hadoop/hadoop-inputs/oreilly-programmingPig/NYSE_daily /user/hadoop/input/oreilly/ 

Answer 1

的错误是目录告诉你，罗阳离子~/hadoop-0.20.204.0,bin/hadoop和bin/start-all.sh不存在。

Did you mean ~/bin，/bin or ~/hadoop-0.20.204.0/bin？如果您的意思是~/hadoop-0.20.204.0/bin，那么第一个失败的cd将解释以下错误。仔细检查文件夹的名称和权限。
