Yiping Han commented on PIG-608:

Alan, I think that's the problem. Everything up to a store or dump is checked 
but if there is an error after that, it will be reported until the previous 
store or dump finished. I don't think this is a duplicate of PIG-607, but I 
agree the fix to PIG-607 might be able to fix this problem (depends on the 
actual solution).

> This is a very usual scenario: 
> We are running a big pig job that contains several hadoop jobs. It has been 
> running for long times and the first hadoop job sucess, then suddenly pig 
> report it found a syntax error in the script after the first hadoop job...we 
> have to repeat from the beginning.
> It would be nice if pig can compile to the end of the script, find all the 
> syntax error, type mismatch, etc., before it really starts execution.
