Daniel Dai commented on PIG-1804:
---------------------------------
Generally looks good. I think there could be a better algebraic sample code
than PyMaxAcc to illustrate the input/output schema of initial/intermed/final
function, which should be the same as Java UDF, and the schema for final is
typically a scalar. "PyAVG" should be a good one.
