Viraj Bhat commented on PIG-1345:
---------------------------------

Which release will PIG:908 be fixed? 

Does it guarantee that if we fix PIG:908, then this issue will be solved?

> For the purpose of easy debugging, I would be nice to find out where  my warnings are
coming from is in the pig script. 
> The only known process is to comment out lines in the Pig script and see if these warnings
go away.

> I think this may need us to keep track of the line numbers of the Pig script (via out
javacc parser) and maintain it in the logical and physical plan.
> It would help users in debugging simple errors/warning related to casting.
> Is this enhancement listed in the  http://wiki.apache.org/pig/PigJournal?
> Do we need to change the parser to something other than javacc to make this task simpler?
