運行簡單shell腳本時出錯

Question

試圖運行一個簡單的shell腳本，其中包含我經常執行的一組命令來設置我的Hadoop環境。首先，我通過'ssh localhost'連接，然後手動執行這些命令，我​​想自動執行此過程，我正在執行以下操作，這會導致下面列出的錯誤。請注意我可以通過命令提示符手動執行這些命令。請幫助我。

我做什麼

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

這將導致以下錯誤

(~($))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

的錯誤是目錄告訴你，羅陽離子~/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，那麼第一個失敗的cd將解釋以下錯誤。仔細檢查文件夾的名稱和權限。
