Shravan Matthur Narayanamurthy commented on PIG-553:

I think the finish method in EvalFunc is just a remnant of our earlier 
code(prev trunk). I do not think we planned to include it because I don't see 
any infrastructure to call it. Though Chris's concern is only in local mode and 
it can be fixed temporarily by just calling a visitor that visits all the 
operators and if a POUserFunc is found calls its finish method. But what do we 
do for the MapRed case? Should we implement a similar behaviour in the close 
method? Do we need to support this kind of an operation for all operators? If 
so then should we also give a place holder for open()?
