Description

Until now, the Pigmix queries were written using the old mapred API.
As a result, some queries were expressed with three concatenated MR jobs instead of one. I rewrote all the queries to match the newer mapreduce API and optimized them on the fly.

This is a continuity work to PIG-3915.
