PigStorage interpreting chararray/bytearray for a tuple element inside a bag as 
float or double
-----------------------------------------------------------------------------------------------

                 Key: PIG-1031
                 URL: https://issues.apache.org/jira/browse/PIG-1031
             Project: Pig
          Issue Type: Bug
          Components: impl
    Affects Versions: 0.5.0
            Reporter: Viraj Bhat
             Fix For: 0.5.0, 0.6.0


I have a data stored in a text file as:

{(4153E765)}
{(AF533765)}

I try reading it using PigStorage as:
{code}
A = load 'pigstoragebroken.dat' using PigStorage() as 
(intersectionBag:bag{T:tuple(term:bytearray)});
dump A;
{code}

I get the following results:

{code}
({(Infinity)})
({(AF533765)})
{code}

The problem seems to be with the method: parseFromBytes(byte[] b) in class 
Utf8StorageConverter. This method uses the TextDataParser (class generated via 
jjt) to interpret the type of data from content, even though the schema tells 
it is a bytearray. 

TextDataParser.jjt  sample code
{code}
TOKEN :
{
...
 < DOUBLENUMBER: (["-","+"])? <FLOATINGPOINT> ( ["e","E"] ([ "-","+"])? 
<FLOATINGPOINT> )?>
 < FLOATNUMBER: <DOUBLENUMBER> (["f","F"])? >
...
}
{code}

I tried the following options, but it will not work as we need to call 
bytesToBag(byte[] b) in the Utf8StorageConverter class.
{code}
A = load 'pigstoragebroken.dat' using PigStorage() as 
(intersectionBag:bag{T:tuple(term)});
A = load 'pigstoragebroken.dat' using PigStorage() as 
(intersectionBag:bag{T:tuple(term:chararray)});
{code}
