Exception running 20newsgroups example
When I try to run the 20 newsgroups example in local mode under cygwin,
mahout creates a work directory under /tmp but then an exception is thrown
indicating that the training data set is not found. It is looking for for it
with a DOS style path. I see the directory and data when I navigate to that
directory.
Can someone please shed some light what I'm missing here? The output is
below:
Thanks
$ sh classify-20newsgroups.sh
Please select a number to choose the corresponding task to run
1. naivebayes
2. sgd
3. clean -- cleans up the work area in /tmp/mahout-work-Administrator
Enter your choice : 1
ok. You chose 1 and we'll use naivebayes

In this case it is looking for a c:\tmp. Do you have one? It does not
come standard with Windows, you have to make it.
This particular code path works, since bin/mahout does not run any
cygwin programs, only Java. I used it a lot.

What you are missing is a Linux compatible environment. Running programs under Cygwin can be pretty difficult because of the path name insanity that often ensues.
