问题
I'm having trouble running Hadoop 1.0.3 on Windows 7 64-bit.
I'm following directions from this link. I've downloaded Cygwin and successfully started the SSH daemon. I unpacked Hadoop into the Cygwin /usr/local folder using Win-Zip 16.5. I edited the hadoop-env.sh to point to my JDK using MetaPad:
export JAVA_HOME="C:\\Program Files\\Java\\jdk1.7.0_02"
I ran dos2unix to make sure that I didn't have any issues with characters.
But when I run the hadoop command in Cygwin terminal to get the version I see this:
$ bin/hadoop version
bin/hadoop: line 2: $'\r': command not found
bin/hadoop: line 17: $'\r': command not found
bin/hadoop: line 18: $'\r': command not found
bin/hadoop: line 49: $'\r': command not found
: No such file or directoryn
bin/hadoop: line 52: $'\r': command not found
bin/hadoop: line 60: syntax error near unexpected token `$'in\r''
'in/hadoop: line 60: `case "`uname`" in
Michael@Michael-PC /usr/local/hadoop
$
Has anyone seen this? Is there an easy correction that I missed?
回答1:
Seems like carriage return difference between unix and windows is causing the problem . Try running dos2unix on the shell script
Go to the hadoop bin directory and try :
dos2unix.exe hadoop.sh
And then try the hadoop command .
