Re: Pig newbie Questions.
Thanks Konstatin.
When using something like this:
        limit myRelation 10;
Is it possible to for the headers/column names to be displayed along with the top 10 rows.
Thanks
Sai

1. Use DESCRIBE *relation_name*
2. Use ILLUSTRATE *relation_name* - that way you'll get a random row.
