Daniel Dai updated PIG-1975:
----------------------------
Attachment: PIG-1975-1.patch
No test added since it is impossible to make legacy LoadCaster compile in new
code. Manual test success.
> Need to provide backward compatibility for legacy LoadCaster (without
> bytesToMap(bytes, fieldSchema))
> -----------------------------------------------------------------------------------------------------

>
> Pig changed LoadCaster interface in 0.9 for typed map (PIG-1876). We change
> bytesToMap(byte[] b, ResourceFieldSchema fieldSchema)
> to
> bytesToMap(byte[] b)
> We should provide backward compatibility for old LoadCaster. If we don't find
> the new bytesToMap, we use the old bytesToMap to convert bytes to map with
> bytearray value. It is still wrong but at least matching the ability of old
> behavior.
