without getting a null error
[ https://issues.apache.org/jira/browse/PIG-2428?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Daniel Dai updated PIG-2428:
----------------------------
Attachment: PIG-2428-0.patch
Seems some part of PIG-1926 does the trick. Attach that part.

> 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
> Attachments: PIG-2428-0.patch

> {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.
