Phabricator commented on HIVE-2592: ----------------------------------- ikabiljo has commented on the revision "HIVE-2592 [jira] ConstantOI doesn't always propagate to UDAF". I do now understand pretty much anything here :) but just a two questions: - is there any general usage of TypeInfo, where ObjectInspector cannot be used? (i.e. should TypeInfo be deprecated and only left for backward compatibility for call-sites) - does this diff/next one tries to fix the issue of try to pass constant OI as partial result to the merge phases?
