Cygwin+Mahout problems with HADOOP_HOME?

Question

Cygwin

I am using hadoop-2.6.0 and mahout-distribution-0.9 and trying to run it all under cygwin on win7 x64.
cygwin terminal:

cd C:/Users/user/Downloads/Hadoop/mahout-distribution-0.9
    export JAVA_HOME="C:/Program Files/Java/jdk1.8.0_31"
    export HADOOP_HOME="C:/Users/user/Downloads/Hadoop/hadoop-2.6.0"
    examples/bin/classify-20newsgroups.sh

I am getting an error:

Please select a number to choose the corresponding task to run
    1. cnaivebayes
    2. naivebayes
    3. sgd
    4. clean -- cleans up the work area in /tmp/mahout-work-user
    Enter your choice : 3
    ok. You chose 3 and we'll use sgd
