Ankit Modi updated PIG-1036:
----------------------------
Attachment: LeftOuterFRJoin.patch
Attaching a new patch.
The join now only supports two way Left join.
Join requires a schema to be mandatory be present on the right side, and it is
used to determine the number of null fields/columns in nullTuple.
As its a two way join we use nullBag instead of an Array of nullBag.
A DataBag is used instead of a Tuple to maintain consistency on the result Type
of ConstantExpression.
