-------------------------------
Summary: Simplify Logical Plans By Removing Unneccessary Identity
Projections
Key: PIG-3123
URL: https://issues.apache.org/jira/browse/PIG-3123
Project: Pig
Issue Type: Improvement
Components: impl
Affects Versions: 0.10.0
Reporter: Nick White
Assignee: Nick White
Fix For: 0.11, 0.12
The TypeCastInserter inserts a LOForeach into a logical plan even if it doesn't
need to make any casts. The attached patch adds a special case to the
TypeCastInserter to skip this behaviour if possible. The patch also refactors
some of the if-instanceof-x-else-if-instanceof-y behaviour into subclasses.
