Dear Wiki user, You have subscribed to a wiki page or wiki category on "Pig Wiki" for change notification.
The "SemanticsCleanup" page has been changed by AlanGates. http://wiki.apache.org/pig/SemanticsCleanup -------------------------------------------------- New page: == Introduction == A number of bugs have been filed against Pig that roughly fall under the area of poorly defined or undefined semantics. In the 0.9 Pig release we would like to take on a number of these issues, clarifying semantics where they are unclear, defining them where they are undefined, and correctly them where they are clearly wrong. This page will classifies the existing bugs and indicates what we believe the proper fix is for them. == Categories == The bugs have been placed into the following categories: * Schema: These are related to schemas that are improperly inferred, etc. * Grammar: Places where the grammar is unclear or produces unexpected results. * Two Level Access: The concept of two level access was introduced long ago to deal with oddities in bag schemas. Ideally we will remove this. At least we have to improve it. == Bug Table == || *JIRA* || *Category* || *Proposed Solution* || || [[https://issues.apache.org/jira/browse/PIG-1627|PIG-1627]] || Schema || Flattening a bag with an unknown schema should produce a record with an unknown schema || || [[https://issues.apache.org/jira/browse/PIG-1584|PIG-1584]] || Grammar || Cogroup inner does not match the semantics of inner join.
