I think this one has been fix in PIG-83

Now the code looks like [GruntParser.java|http://svn.apache.org/repos/asf/incubator/pig/trunk/src/org/apache/pig/tools/grunt/GruntParser.java] :
{code:java}
            catch(Exception e)
            {
                log.error(e.getMessage());
            }
{code}
You should get the full stacktrace when an error occurs.

> I suggest grunt should be more helpful with user errors. I just did one (a stupid one) and it took my too long to figure out the problem, since grunts error message was just not giving me a good hint:
> grunt> A = LOAD '/pigtestData.tsv' USING PigStorage(',') AS (user,age,cat);
> grunt> B = FILTER A BY cat == 'book';
> grunt> dump B;
> For input string: "book"
> Experts will see that I tried to use == instead of eq, however especially new users could get a little confused. 
> I see two chances add Error Number and  descriptive texts (Oracle style) - this quite a lot of work, or for now I suggest to simply dump the full exception text.
> At least for this early stage it would developers and users to find problems faster.
