implement typechecking and lineage tracking on new logical plan ---------------------------------------------------------------
Key: PIG-1847 URL: https://issues.apache.org/jira/browse/PIG-1847 Project: Pig Issue Type: Task Affects Versions: 0.8.0 Reporter: Thejas M Nair Assignee: Thejas M Nair Fix For: 0.9.0 In 0.8, TypeCheckingVisitor works on the old logical plan, before it is translated to new logical plan. The TypeCheckingVisitor checks the types in expressions, adds casts and tracks lineage for identifying which load function's LoadCaster interface is to be used to convert bytearrays into other types. As the old logical plan is going away in 0.9, this functionality needs to be added for new plan. -- This message is automatically generated by JIRA. - For more information on JIRA, see: http://www.atlassian.com/software/jira
