> Key: PIG-1925
> URL: https://issues.apache.org/jira/browse/PIG-1925
> Project: Pig
> Issue Type: Bug
> Affects Versions: 0.9.0
> Reporter: Xuefu Zhang
> Assignee: Xuefu Zhang
> Fix For: 0.9.0
>
> Attachments: PIG-1925-1.patch, PIG-1925.patch

>
> When Parser emits an error from one of the tree parsers (like AST validation
> or plan generation), Line number is missing or printed as Line 0:0. Further
> investigation shows that Antlr 3.2 isn't able to report the correct line
> number and line offset. We need to address it in Pig code.
> The following is an example.
> grunt> A = load 'x' as (u, v, u, w);
> 2011-03-21 10:04:44,486 [main] ERROR org.apache.pig.tools.grunt.Grunt - ERROR
> 0: Duplicated alias in schema: u
> It's desirable to have line number/offset in such kind of error messages.
