Question

尝试运行一个简单的shell脚本，该脚本由我常规执行以设置Hadoop环境的一组命令组成。首先，我在手动执行这些命令之前通过' ssh localhost '进行连接，我想自动执行此过程，我正在执行以下操作，导致下面列出的错误。请注意我可以从命令提示符手动执行这些命令。请帮帮我。

我做了什么

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

这会导致以下错误

(~($))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

hadoop-startup-script.sh

的内容

#! /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

错误告诉您位置~/hadoop-0.20.204.0，bin/hadoop和bin/start-all.sh不存在。

您的意思是~/bin，/bin还是~/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会解释以下错误。仔细检查文件夹的名称和权限。
