運行簡單shell腳本時出錯

Question

試圖運行一個簡單的shell腳本，該腳本由我常規執行以設置Hadoop環境的一組命令組成。 首先，我在手動執行這些命令之前通過' ssh localhost '連接，我想自動執行此過程，我正在執行以下操作，導致下面列出的錯誤。 請注意我可以從命令提示符手動執行這些命令。 請幫幫我。

我做了什么

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

這會導致以下錯誤

(~($))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

hadoop-startup-script.sh的內容

#! /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

錯誤告訴您位置~/hadoop-0.20.204.0 ， bin/hadoop和bin/start-all.sh不存在。

你是說~/bin ， /bin還是~/hadoop-0.20.204.0/bin ？ 如果您的意思是~/hadoop-0.20.204.0/bin那么第一個失敗的cd解釋以下錯誤。 仔細檢查文件夾的名稱和權限。
