------------------------------------------
Summary: Remove SqlSyntax.FUNCTION_STAR from AVG and SUM functions
Key: HIVE-29399
URL: https://issues.apache.org/jira/browse/HIVE-29399
Project: Hive
Issue Type: Task
Reporter: Stamatis Zampetakis
Assignee: Stamatis Zampetakis
The AVG (HiveSqlAverageAggFunction) and SUM (HiveSqlSumAggFunction) functions
don't support the special FUNCTION_STAR syntax and trying to write queries
including AVG(*) or SUM(*) currently fail (see invalid_avg_syntax.q,
invalid_sum_syntax.q tests).
The SqlSyntax.FUNCTION_STAR syntax for SUM/AVG was incorrectly set by
HIVE-29339 so this ticket is a follow-up to restore the previous and correct
behavior.
