["Gianmarco De Francisci Morales (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/PIG-1926?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Gianmarco De Francisci Morales updated PIG-1926:
------------------------------------------------

    Description: 
Currently, Limit, Sample only takes a constant. It would be better we can use a scalar in the place of constant. Eg:

{code}
a = load 'a.txt';
b = group a all;
c = foreach b generate COUNT(a) as sum;
d = order a by $0;
e = limit d c.sum/100;
{code}

This is a candidate project for Google summer of code 2011. More information about the program can be found at http://wiki.apache.org/pig/GSoc2011
