Chao Wang updated PIG-1351: --------------------------- Attachment: PIG-1351.patch > [Zebra] No type check when we write to the basic table > ------------------------------------------------------ > > Key: PIG-1351 > URL: https://issues.apache.org/jira/browse/PIG-1351 > Project: Pig > Issue Type: Improvement > Affects Versions: 0.6.0, 0.7.0, 0.8.0 > Reporter: Chao Wang > Assignee: Chao Wang > Fix For: 0.8.0 > > Attachments: PIG-1351.patch > > > In Zebra, we do not have any type check when writing to a basic table. > Say, we have a schema: "f1:int, f2:string", > however we can write a tuple ("abc", 123) without any problem, which is > definitely not desirable. > To overcome this problem, we decide to perform certain amount of type > checking in Zebra - We check the first row only for each writer. > This only serves as a sanity check purpose in cases where users screw up > specifying the output schema. We do NOT perform a rigorous type checking for > all rows for apparently performance concerns. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
