I am trying to set JAVA_HOME in env.sh in hadoop. I am using cygwin on Windows 7.
I have edited the env.sh as :
export JAVA_HOME= "/cygdrive/C/Program Files/Java/jdk1.6.0_26"
In environment variables I have set JAVA_HOME as C:\Program Files\Java\jdk1.6.0_26
And the path as %JAVA_HOME%\bin;c:\cygwin\bin;c:\cygwin\usr\sbin
But still I am getting these errors.
/cygdrive/d/hadoop-1.2.1/libexec/../conf/hadoop-env.sh: line 2: $'\r': command not found

Error: JAVA_HOME is not set.
I have checked everything possible on this website but still facing the problem.
Use export JAVA_HOME="C:/PROGRA~2/Java/jdk1.6.0_03" #for 32 bit Java arch
Use export export JAVA_HOME="C:/PROGRA~1/Java/jdk1.6.0_03" #for 64 bit Java arch
This will fix your problem... The answer I am giving is pretty late but it will help others who are beginners facing the same problem.
use C:\"Program Files"\Java\jdk1.6.0_26 instead, that should solve the java problem.

cygwin warning:

Preferred POSIX equivalent is: /cygdrive/c/CYGWIN~1/home/user/HADOOP~1.1/build/native
CYGWIN environment variable option "nodosfilewarning" turns off this warning.

can anyone help me to remove this error.
thank you
It seems like you have a problem with your newline characters which prevents hadoop to find your java binaries. See this question on stackoverflow.
Try running dos2unix on your hadoop-env.sh.
I put jdk in "E:/cygwin/jdk7",so I updated JAVA_HOME both in environment and hadoop-env.sh to it.
but when I first run ./hdfs namenode -format,I got this:
$ ./hdfs namenode -format

I changed core-site.xml、hdfs-site.xml、mapred-site.xml、yarn-site.xml like hundred times,but it still doesn't work
I appreciate if anyone give any suggestions!

Error: JAVA_HOME is not set.
When I am doing echo $JAVA_HOME, it is giving C:\Program Files\Java\jdk1.6.0_26.
I have checked everything possible on this website, but still facing the problem.
i have tried all possible solutions through google but still not working
i am not getting what is this command not found error from hadoop-env.sh and bin/java not such a directory,
Here is hadoop-env.sh
export JAVA_HOME=/cygdrive/c/Java/jre6
export JAVA_HOME=c:/Java/jre6
Here is my error bellow

Go to environment variable and then advance setting
Go to user variable and setVariable JAVA_HOME and there Value C:\Java\sunjdk6.0.24
Then go to Path and set cygwin path c:\cygwin\bin;c:\cygwin\usr\bin
DO it if not done erlier, If you still facing problem then see Link for Hadoop installation on windows and follow every steps.
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?
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 .
