Santhosh Srinivasan updated PIG-303:
------------------------------------
Attachment: pig_type_to_bytearray.patch
The patch (pig_type_to_bytearray.patch) includes the following:
1. The load function interface is extended to include toBytes, a method that
will convert Pig Types to the appropriate byte representation that can be used
with the bytesToPigType routine
2. The methods are implemented in all the classes that implement the load
function interface, i.e., PigStorage, BinStorage, TextLoader, private classes
used in the unit test cases, etc.
3. A text data parser that converts text data to Pig Types
4. Unit test cases for the conversion routines and the casts.
5. Helper methods in DataType.java for checking equal byte arrays and
converting Pig Map to strings.
TODO:
The byte arrays are parsed as strings as the parser cannot distinguish between
the two.
Unit test cases that still fail are:
