Trying to access non-existent > column: 3. Schema {B::group: bytearray,long,bytearray} has 3 column(s). > Apparently Pig gets confused, and thinks it knows the schema for C (a single > bytearray column). -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
