Lars Francke commented on HIVE-4934:
------------------------------------
I just wanted to add the clarification and saw that you've been - once more -
faster than me. Thanks for helping out!
> Improve documentation of OVER clause
> ------------------------------------
>
> Key: HIVE-4934
> URL: https://issues.apache.org/jira/browse/HIVE-4934
> Project: Hive
> Issue Type: Bug
> Reporter: Lars Francke
> Assignee: Lars Francke
> Priority: Minor
>
> {code}
> CREATE TABLE test (foo INT);
> SELECT ntile(10), foo OVER (PARTITION BY foo) FROM test;
> FAILED: SemanticException org.apache.hadoop.hive.ql.metadata.HiveException:
> Only COMPLETE mode supported for NTile function
> SELECT foo, ntile(10) OVER (PARTITION BY foo) FROM test;
> ...works...
> {code}
> I'm not sure if that is a bug or necessary. Either way the error message is
> not helpful as it's not documented anywhere what {{COMPLETE}} mode is. A
> cursory glance at the code didn't help me either.
> Edit: It is not a bug, it wasn't clear to me that the OVER clause only
> applies to the directly preceding function.
