Pig newbie Questions.

1. How to display the column names in pig in a console.

2. When using dump, can we just get the top 10 rows rather than all other rows.

Your help is appreciated.

Thanks
Sai

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.
