class	POSplit The MapReduce Split operator.
class	POStore The store operator which is used in two ways: 1) As a local operator it can be used to store files 2) In the Map Reduce setting, it is used to create jobs from MapReduce operators which keep the loads and stores in the Map and Reduce Plans till the job is created
