> Reporter: Tongjie Chen

> Parquet Pig reads footer in client side, to calculate splits and retrieve

> In HCatalog environment, if there are large number of files generated by
> Hive, Parquet-Pig will spend significant chunk of time processing those
> footers in client side (before job is submitted to cluster).
