Dude, do not be so frustrating, and I've just started going to use windows as a development environment, cygwin use them very troublesome, hadoop rely a lot of things need to go to download. I put into the development environment ubuntu, this system is very good, and the latest is 12.10, you can upload on your computer dual system a try, I do not recommend using wubi installation.
------ Solution ---------------------------------------- ----
configure hadoop on ubuntu it very easy to see the official documentation can get cygwin does have some trouble
------ Solution -------- ------------------------------------
Obviously ah your java jdk path Configuration Error ah in hadoop-env.sh configuration error in the study suggest that you install Ubuntu linux hadoop sooner or later had to get on
