Subject [jira] Commented: (PIG-98) grunt should show full exception stack
Date Wed, 20 Feb 2008 01:00:43 GMT

    [ https://issues.apache.org/jira/browse/PIG-98?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12570518#action_12570518

Alan Gates commented on PIG-98:

I agree with you that much of our error reporting is horrible.  However, we are trying to
get hadoop specific stuff out of the front end of pig.  So we don't want to use hadoop's stringifyException
function in grunt.  So we'll need to lookfor for another way to mitigate this short term before
we solve it long term.

> 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.
