From my map function I create Tuple2Integer, Integer pairs. Now I want to
reduce them, and get something like Tuple2Integer, Listlt;Integer.
The only way I found to do this was by treating all variables as String, and
in the reduceByKey do
/return a._2 + , + b._2/ //in which both are numeric
If you mean you have (key,value) pairs, and want pairs with key, and
all values for that key, then you're looking for groupByKey
