Subject [jira] Updated: (PIG-489) Translate project( * ) in operators that have a nested plan
Date Fri, 10 Oct 2008 21:33:44 GMT

Santhosh Srinivasan updated PIG-489:

    Attachment: PIG-489.patch

Attached patch, adds a new visitor that translates project( * ) inside nested plans of foreach,
cogroup and sort if the project's input has a schema and if the return type of the project
is not a bag.

All unit test cases except TestStreaming pass. TestStreaming passes when run in isolation.

> Currently, the project( * ) operator results in the generation of a tuple schema even
when the schema of the project's input is known. This is confusing to the user and should
be remedied. In addition this will address a bug in Pig-335 which prevents tracking lineage
