Running TPC-H On Pig

For a project of class CPS 216, we developed a whole set of Pig scripts for TPC-H. Our goals are:

1) identifying the bottlenecks of Pig's performance especially of its relational operators,

2) studying how to write efficient scripts by making full use of Pig Latin's features,

3) comparing with Hive's TPC-H results for verifying both 1) and 2).
