Daniel Dai commented on PIG-4092:
---------------------------------
Pig's ParquetLoader is a wrapper. It's true PARQUET-397 implements
LoadPredicatePushdown in parquet's ParquetLoader, but we still need to declare
the interface and pass the method call to the wrapped ParquetLoader, this is
not done, a simple patch is needed.
