Subject Re: Unit Tests Failed
Date Fri, 17 Apr 2009 00:44:36 GMT
I do not believe that the Mahout code itself requires Cygwin. Hadoop 
requires it on Windows boxes so that it can issue e.g. chmod commands to 
a uniform OS interface. Our unit tests utilize Hadoop to test their 
parallel versions and, if Cygwin is not installed, those tests will fail 
and the jar will not be built. You will have the same problem running 
any of the parallel versions on a Windows box without Cygwin.

Is there an issue with using Cygwin?
