Date Fri, 09 Jul 2010 08:43:50 GMT
Hello,

I’am a new Mahout’s user and i work on the recommender system.

I installed Mahout 2 on my windows machine but when I execute mvn install I
have the following message and the file .job is not created under the
$MAHOUT_HOME/core directory .

 

This is the error message:
