Alan Gates created HIVE-4214:
--------------------------------
Summary: OVER accepts general expression instead of just function
Key: HIVE-4214
URL: https://issues.apache.org/jira/browse/HIVE-4214
Project: Hive
Issue Type: Bug
Components: PTF-Windowing
Affects Versions: 0.11.0
Reporter: Alan Gates
The query:
select s, i, avg(d) / 10.0 over (partition by s order by i) from over100k;
runs (and produces meaningless output).
Over should not allow the arithmetic expression. Only a UDAF or PTF function
should be valid there. The correct way to write this query should be
select s, i, avg(d) over (partition by s order by i) / 10. 0 from over100k;
