Get the most similar users with ItemSimilarityJob.

[WangRamon]

Hi All I have a use case which is trying to find the most similarity users. So 
the input data is still in format [USER_ID, ITEM_ID, PREF], I think I can use 
ItemSimilarityJob in Mahout 0.6, although the name is Item Similarity, by 
reading the code I find if I change the input to be [ITEM_ID, USER_ID, PREF], I 
should get the desired result which is the USER_ID and its similar user's ID, 
am I correct? Thanks in advance.   Cheers  Ramon
