In pig9, can't have limit(order by) without getting a null error
----------------------------------------------------------------
Key: PIG-2428
URL: https://issues.apache.org/jira/browse/PIG-2428
Project: Pig
Issue Type: Bug
Affects Versions: 0.9.0, 0.9.2
Reporter: Jonathan Coveney
{code}
a = load 'thing' as (x:int);
b = group a by x;
c = foreach b generate group as x, COUNT(a) as count;
d = limit (order c by count DESC) 2000;
describe d;
{code}
This gives the following error:
2011-12-13 13:56:32,144 [main] ERROR org.apache.pig.tools.grunt.Grunt - ERROR
1005: No plan for d to describe
In trunk, it ran without issue. Not sure what the difference is, but it'd be
nice to patch 0.9.2 since a lot of people (including amazon!) are using pig 9
now.
