Lars Francke updated HIVE-4934:
-------------------------------
Description:
{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.
