Link casting errors in POCast to actual lines numbers in Pig script
-------------------------------------------------------------------
Key: PIG-1345
URL: https://issues.apache.org/jira/browse/PIG-1345
Project: Pig
Issue Type: Improvement
Components: impl
Affects Versions: 0.6.0
Reporter: Viraj Bhat
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?
