> {{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).
