Daniel Dai updated PIG-989: --------------------------- Attachment: PIG-989-1.patch Patch to fix error message > Allow type merge between numerical type and non-numerical type > -------------------------------------------------------------- > > Key: PIG-989 > URL: https://issues.apache.org/jira/browse/PIG-989 > Project: Pig > Issue Type: Bug > Components: impl > Affects Versions: 0.5.0 > Reporter: Daniel Dai > Attachments: PIG-989-1.patch > > > Currently, we do not allow type merge between numerical type and > non-numerical type. And the error message is confusing. > Eg, if you run: > a = load '1.txt' as (a0:chararray, a1:chararray); > b = load '2.txt' as (b0:long, b1:chararray); > c = join a by a0, b by b0; > dump c; > And the error message is "ERROR 1051: Cannot cast to Unknown" > We shall: > 1. Allow the type merge between numerical type and non-numerical type > 2. Or at least, provide more meaningful error message to the user -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
