> Parser should detect tuple field number problems when possible

>                 Key: PIG-53
>                 URL: https://issues.apache.org/jira/browse/PIG-53
>             Project: Pig
>          Issue Type: Sub-task

> In the following:
> A = load 'foo';
> B = foreach A generate $1, $2;
> C = foreach B generate $2;
> The parse should be able to detect that the last line is referencing a 
> non-existant field. It cannot do the check for the 2nd line since it doesn't 
> know the number of fields of the tuples of A, but it can for the last line 
> since it know that tuples of B have 2 fields.
> It is much easier to figure out what is going on when the error is detected 
> at parse time rather than runtime.
