PORelationToExprProject should create a NonSpillableDataBag to create empty bags
--------------------------------------------------------------------------------
Key: PIG-775
URL: https://issues.apache.org/jira/browse/PIG-775
Project: Pig
Issue Type: Bug
Affects Versions: 0.2.0
Reporter: Pradeep Kamath
Assignee: Pradeep Kamath
Priority: Minor
Fix For: 0.3.0
PORelationToExprProject currently uses "BagFactory.newDefaultBag()" to create
an empty bag in cases where it has to send an empty bag on EOP - each such
empty bag created will be registered with the SpillableMemoryManager as a
spillable bag. Since it is an empty bag, it really should not be registered as
a spillable bag. For this, NonSpillableDataBag can be used.
