Key: PIG-1737 URL: https://issues.apache.org/jira/browse/PIG-1737 Project: Pig Issue Type: Bug Components: impl Affects Versions: 0.8.0 Reporter: Daniel Dai Assignee: Daniel Dai Fix For: 0.8.0 Pig fail when foreach schema does not match user defined schema with the NPE. The error message should be enhanced. Eg: {code} a = load '1.txt' as (a0, a1, a2); b = group a by (a0, a1); c = foreach b generate flatten(group) as c0; dump c; {code} flatten(group) contains 2 items, user cannot name it into c0 alone. However, Pig die with NPE, which is clueless to the user. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
