casting relation to scalar- problem with handling of data from non PigStorage 
loaders
-------------------------------------------------------------------------------------

                 Key: PIG-1595
                 URL: https://issues.apache.org/jira/browse/PIG-1595
             Project: Pig
          Issue Type: Bug
            Reporter: Thejas M Nair
            Assignee: Thejas M Nair
             Fix For: 0.8.0


If load functions that don't follow the same bytearray format as PigStorage for 
other supported datatypes, or those that don't implement the LoadCaster 
interface are used in 'casting relation to scalar' (PIG-1434), it can cause the 
query to fail or create incorrect results.

(I will add an example and elaborate further).
