[Divya Gehlot]

Hi,
I have a pig script which return field as
 Key=Val&Key=Val&Key=Val&Key=Val&Key=Val whose schema  is defined as
data:chararray in my pig script
Can I use java UDF to return a tuple of Key Value Pair.

Would really appreciate if somebody help me point to some guide or example
of this kind of scenario.


Thanks
