which hadoop version are you using??

Please specify the error.

[Midhun Suraj]

Hadoop version : hadoop-0.22.0

please check  that image.this the error.

I think i made mistake in editing the configuration files.

i edit  cygwin's profile fie for adding JAVA_HOME

and then hadoop/bin -hadoop-config

then hadoop/config -hadoop-env

this error is always getting for any action

cygpath: can't convert empty path 

Thanks

Hi Midhun,

    i will give idea regarding this problem.copy the java folder from program files and paste it from cygwin drive like(/usr/local/java).then follow the below steps in cygwin

1.cd ~

2.vi .bashrc(add the below two lines at the end of the file)

   export JAVA_HOME="/usr/local/java"

   export PATH="$PATH;$JAVA_HOME/bin"

3. source .bashrc

4.go to hadoop configuration folder

 5.vi hadoop-env.sh(edit the below line like this)

     export JAVA_HOME="/usr/local/java"

  6.go to bin foolder in hadoop

  7. vi hadoop(edit the below lines)

         CLASSPATH=`cygpath -wp "$CLASSPATH"`

Thanks and Regards
