Xuefu Zhang commented on PIG-1947: ---------------------------------- Because currently a user script is parsed by at least two parsers (grunt parser and query parser), the line number is lost or incorrect reported due to a simplistic design. To fully address the problem, the following is required: 1. Grunt parser needs to be changed to passing more information to query parser about the source location of each line of the query. Right now, only a line number is passed alone. 2. Query parser needs a more sophisticated design to capture the source location of the script received from grunt parser. Currently, it caches the script lines in a list, which cannot fully recover the locations when query is subsequently parsed. 3. A clear semantic of line number is to be defined in interactive mode, especially in case of invalid query lines. > Incorrect line number is reported during parsing > ------------------------------------------------ > > Key: PIG-1947 > URL: https://issues.apache.org/jira/browse/PIG-1947 > Project: Pig > Issue Type: Bug > Affects Versions: 0.9.0 > Reporter: Xuefu Zhang > Assignee: Xuefu Zhang > Fix For: 0.10 > > Attachments: PIG-1947-2.patch, PIG-1947.patch > > > In case of errors in script, Pig parser doesn't report correct the line > number always.
