not able to run pig on windows 7 using cygwin - windows

Question

I configured pig as directed in the documentation.
Enviornment: Windows 7, Hadoop-0.20.2, pig 0.13.0, Cygwin
But when i type pig (mapreduce) on the command prompt it just displays below thing. I am not sure whether pig is started or not. I don't see GRUNT shell to execute script.
Btw, Hadoop is running on the same node.
Can someone please help?
$ pig
Find hadoop at /hadoop-0.20.2/bin/hadoop
dry run:

/hadoop-0.20.2/bin/hadoop jar C:\cygwin64\PIG-01~1.0/pig-withouthadoop-h2.jar
when i run in debug mode, i see this exception. This is because Hadoop Jar is not set.
