there is no Random Forest impl on Spark in Mahout yet. Ml-lib has a Random

I have some questions regarding vectorization.
Here is my Pig script snippet.
AU = FOREACH A GENERATE myparser.myUDF(param1, param2); STORE AU into

AU has the following format:
(userid, (item_view_history))
(27,(0,1,1,0,0))(28,(0,0,1,0,0))(29,(0,0,1,0,1))(30,(1,0,1,0,1))
Trying to figure that out now. Will keep you posted.
