not able to run pig on windows 7 using cygwin

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_CLASSPATH: C:\\cygwin64\\pig-0.13.0\\conf;C;C:\\Program Files\\Java\\jdk1.6.0_25\\lib\\tools.jar;C;C:\\cygwin64\\hadoop-0.20.2\\conf;C:\\cygwin64\\pig-0.13.0\\lib\\accumulo-core-1.5.0.jar;C:\\cygwin64\\pig-0.13.0\\lib\\accumulo-fate-1.5.0.jar;C:\\cygwin64\\pig-0.13.0\\lib\\accumulo-server-1.5.0.jar;C:\\cygwin64\\pig-0.13.0\\lib\\accumulo-start-1.5.0.jar;C:\\cygwin64\\pig-0.13.0\\lib\\accumulo-trace-1.5.0.jar;C:\\cygwin64\\pig-0.13.0\\lib\\avro-1.7.5.jar;C:\\cygwin64\\pig-0.13.0\\lib\\avro-mapred-1.7.5.jar;C:\\cygwin64\\pig-0.13.0\\lib\\avro-tools-1.7.5-nodeps.jar;C:\\cygwin64\\pig-0.13.0\\lib\\groovy-all-1.8.6.jar;C:\\cygwin64\\pig-0.13.0\\lib\\hbase-0.94.1.jar;C:\\cygwin64\\pig-0.13.0\\lib\\jruby-complete-1.6.7.jar;C:\\cygwin64\\pig-0.13.0\\lib\\js-1.7R2.jar;C:\\cygwin64\\pig-0.13.0\\lib\\json-simple-1.1.jar;C:\\cygwin64\\pig-0.13.0\\lib\\jython-standalone-2.5.3.jar;C:\\cygwin64\\pig-0.13.0\\lib\\piggybank.jar;C:\\cygwin64\\pig-0.13.0\\lib\\protobuf-java-2.4.0a.jar;C:\\cygwin64\\pig-0.13.0\\lib\\zook eeper-3.4.5.jar:C:\\cygwin64\\PIG-01~1.0/pig-withouthadoop-h2.jar: HADOOP_OPTS: -Xmx1000m -Dpig.log.dir=C:\\cygwin64\\PIG-01~1.0\\logs -Dpig.log.file=pig.log -Dpig.home.dir=C:\\cygwin64\\PIG-01~1.0\\ HADOOP_CLIENT_OPTS: -Xmx1000m -Dpig.log.dir=C:\\cygwin64\\PIG-01~1.0\\logs -Dpig.log.file=pig.log -Dpig.home.dir=C:\\cygwin64\\PIG-01~1.0\\ /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.
