Shravan Matthur Narayanamurthy updated PIG-161:
-----------------------------------------------

    Status: Patch Available  (was: Open)

The base classes for the physical operators, the comparison operators, 
POFilter, POProject, ConstantExpr, PhysicalPlan, ExprPlan and their 
corresponding visitors are available in this patch. This also includes changes 
to the Operator, OperatorPlan and PlanVisitor to make them typed. I have 
checked that it does not affect any previous code. So if people want to use it 
they can.

> Rework physical plan
