Key: HIVE-2964
URL: https://issues.apache.org/jira/browse/HIVE-2964
Project: Hive
Issue Type: Improvement
Reporter: Navis
Assignee: Navis
Priority: Minor
Currently, TOK_FUNCTIONSTAR type UDAFs are provided with empty OI at init time
and is sufficient for sum, the only UDAF accepts START as a parameter. But for
some UDAFs, it is needed to know all OIs that can be used to access values of a
row.
