[jira] [Updated] (HIVE-12734) Remove redundancy in HiveConfs serialized to UDFContext

     [ https://issues.apache.org/jira/browse/HIVE-12734?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

>                 URL: https://issues.apache.org/jira/browse/HIVE-12734
>             Project: Hive
>          Issue Type: Bug
>    Affects Versions: 1.2.1, 2.0.0

> {{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).
