Subject [jira] [Commented] (HIVE-12734) Remove redundancy in HiveConfs serialized to UDFContext
Date Mon, 01 Feb 2016 21:48:40 GMT

    [ https://issues.apache.org/jira/browse/HIVE-12734?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15127104#comment-15127104

Sergey Shelukhin commented on HIVE-12734:
-----------------------------------------

Removing 2.0 from target versions as RC0 has been cut. Please -1 the RC, reinstate the version
and make this a blocker if that is not acceptable :)

> {{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.
