Santhosh Srinivasan updated PIG-303:
------------------------------------
Attachment: remove_cast_to_bytearray.patch
Casts to bytearray are no longer allowed. The patch includes the following:
1. Parser throws an exception when explicit casts to bytearray are seen
2. Type checker throws an exception when implicit casts to bytearray are used
3. The load interface does not have toBytes(PigType) methods
4. The toBytes method in Utf8StorageConverter.java, BinStorage.java and
TextLoader.java are retained for future use
5. A text data parser that converts text data to Pig Types
6. Unit test cases for the conversion routines and the casts.
7. 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 tests that still fail are:
