Shouldn't the jar containing parquetLoader and parquetStorer classes
be directly on pig's classpath by default in pig0.12?
When I try using parquet load:
grunt> A = LOAD '/region.parquet' USING parquet.pig.ParquetLoader AS
(R_REGIONKEY:int,R_NAME:chararray,R_COMMENT:chararray);

Once I add the parquet jars it does seem to go beyond this stage.
