Ankur commented on MAHOUT-103:
------------------------------

I skimmed through your version and what's present in .item package. Few 
immediate things that come to mind are
1. Moving to AbstractJob
2.  Re-factoring to separate map,reduce and job classes. Personally I hate that 
coz it the code base just bloats when number of M/R jobs increase.

I have been trying to setup my idea using IntelliJ.codestyle.xml provided by 
mahout cwiki. I placed the file under idea_home/config/codeStyles and restarted 
idea but it still does not an import option  in File->Settings->Code Style.  
Idea shows following messages in the back ground
Field not copied JAVA_INDENT_OPTIONS
Field not copied JSP_INDENT_OPTIONS
Field not copied XML_INDENT_OPTIONS
Field not copied OTHER_INDENT_OPTIONS
Field not copied FIELD_TYPE_TO_NAME
Field not copied STATIC_FIELD_TYPE_TO_NAME
Field not copied PARAMETER_TYPE_TO_NAME
Field not copied LOCAL_VARIABLE_TYPE_TO_NAME
Field not copied PACKAGES_TO_USE_IMPORT_ON_DEMAND
Field not copied IMPORT_LAYOUT_TABLE

I am using v 8.1.4

Once i set this up, I am gonna look at your version and what's there in .item 
package

> Nearest neighborhood type queries for users/items can be answered efficiently 
> and effectively by analyzing the co-occurrence model of a user/item w.r.t 
> another. This patch aims at providing an implementation for answering such 
> queries based upon simple co-occurrence counts.
