I have downloaded the Hadoop 0.20.2 and Eclipse 3.6 because I want to use the plugin. I am
also using cygwin. However, I set the environment variable for JAVA_HOME and added the c:\cygwin\bin;c:\cygwin\usr\bin
to the PATH variable but I still get the error below when trying to start the Hadoop. This
is based on the instructions to edit the file conf/hadoop-env.sh to define at least JAVA_HOME
to be the root of your Java installation which I changed to "export JAVA_HOME=/cygdrive/c/Program\
Files\ \(x86\)/Java/jdk1.6.0_26" with no success. I added the \ to escape special characters.

at the link above but each time I run into errors with the plugin or not recognizing the import
