I am trying to use Mahout in an application running on Windows. I want to build clusters from a lucene index using k-means.

As soon as I have to create sequence files (creating vectors from a lucene index), I get a Hadoop-Exception, since Hadoop makes command line calls to programs unknown in a Windows environment (e.g. chmod). Running in Cygwin is not an option, since I want to be able to run the App from eclipse.

So my question is

is there a way to avoid having to create sequence files to retrieve my vectors from a lucene index?

or is there a way to create sequence files in a Windows environment?
