Subject [jira] [Commented] (PIG-1947) Incorrect line number is reported during parsing
Date Thu, 31 Mar 2011 18:34:05 GMT

    [ https://issues.apache.org/jira/browse/PIG-1947?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13014127#comment-13014127

Xuefu Zhang commented on PIG-1947:
----------------------------------

The problem is of partly regression (line #) and partly heritage (column #). I think I can
put a fix in QueryParser, which may not be perfect but eliminating the need of touching Grunt
parser at this time. Then, we can revisit the issue in 0.10.

> In case of errors in script, Pig parser doesn't report correct the line number always.
For example:
> script:
> A = load 'x' as ( u:int, v:chararray );
> sh ls -l;
> B = foreach A generate u + v;
> store B into 'y';
> error reported:
> 2011-03-30 17:48:04,649 [main] ERROR org.apache.pig.tools.grunt.Grunt - ERROR 1039: <file
line.pig, line 2, column 25> (Name: Add Type: int Uid: 7)incompatible types in Add Operator
left hand side:Unknown right hand side:Unknown
> Incorrect line number is also reported when a single line contains multiple Pig statement,
such as:
> A = load 'x' as( u:int, v:chararray); B = foreach A generate u + v;
> store B into 'y';
