Daniel Dai commented on PIG-1090:
---------------------------------

Regarding to PIG-1090-4.patch, In LOLoad.getSchema, we shall remove the lines 
to setup "pig.loader.signature". In the new design, UDF writers should use 
signature inside the LoadFun to keep track of signature rather than the 
Configuration.

Other part relate to signature and push projection looks good to me.

> Update sources to reflect recent changes in load-store interfaces
