Viraj Bhat updated PIG-1031:
----------------------------
Description:
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:
({(Infinity)})
({(AF533765)})
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}
