Ying He updated PIG-1135:
-------------------------

    Attachment: PIG_1135.patch

if reducer index is greater than 128, the index of streaming table becomes 
negative because byte is used as data type.
It is fixed by changing partition index from byte to integer. 

> skewed join partitioner returns negative partition index
