    Description

      HCatLoader lands up serializing one HiveConf instance per table-alias, to Pig's UDFContext. This lands up bloating the UDFContext.

      To reduce the footprint, it makes sense to serialize a default-constructed HiveConf once, and one "diff" per HCatLoader. This should reduce the time taken to kick off jobs from pig -useHCatalog scripts.

      (Note_to_self: YHIVE-540).
